        The POST method creates a new VNF instance resource based on a VNF package that is onboarded and in
        "ENABLED" state.
        This method shall follow the provisions specified in the tables 5.4.2.3.1-1 and 5.4.2.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        As the result of successfully executing this method, a new "Individual VNF instance"
        resource as defined in clause 5.4.3 shall have been created, and the value of the
        "instantiationState" attribute in the representation of that resource shall be "NOT_INSTANTIATED".
        A notification of type VnfIdentifierCreationNotification shall be triggered as part of successfully
        executing this method as defined in clause 5.5.2.18.
        When initiating the creation of a VNF instance resource, the passed metadata values can differ from 
        the default values for metadata, if any, declared in the VNFD.
        The VNFM shall apply the "metadata" attributes in the "CreateVnfRequest" data structure in the payload 
        body to the "metadata" attribute in the "VnfInstance" data structure on top of the default values that 
        were obtained from the VNFD according to the rules of JSON Merge Patch (see IETF RFC 7396). 
        For all metadata keys defined in the VNFD, the VNFM shall ensure that the content of the resulting 
        "metadata" attributes is valid against the data type definitions in the VNFD. The absence of a metadata 
        item that is marked "required" in the VNFD shall not be treated as an error. In case a "metadata" child 
        attribute is not defined in the VNFD, the VNFM shall consider it valid in case it is a valid JSON structure. 
        In case of an error, the operation shall be rejected with a "422 Unprocessable Entity" error.

        This method modifies an "Individual VNF instance" resource.
        Changes to the VNF configurable properties are applied to the configuration in the VNF instance,
        and are reflected in the representation of this resource.
        Other changes are applied to the VNF instance information managed by the VNFM, and are reflected
        in the representation of this resource.
        This method shall follow the provisions specified in the tables 5.4.3.3.4-1 and 5.4.3.3.4-2
        for URI query parameters, request and response data structures, and response codes.
        The steps and conditions that apply as the result of successfully executing this method are
        specified in clause 5.4.1.2.
        The VNFM shall apply the "metadata", "extensions" and "vnfConfigurableProperties" attributes in the 
        "VnfInfoModificationRequest" data structure in the payload body to the existing "extensions" and
        "vnfConfigurableProperties" attributes from the "VnfInstance" data structure according to the 
        rules of JSON Merge Patch (see IETF RFC 7396).
        The VNFM shall ensure that the content of the child attributes of the resulting "metadata", "extensions" 
        and "vnfConfigurableProperties" attributes is valid against the data types definitions of these child 
        attributes in the VNFD. 

        In case a "metadata" child attribute is not defined in the VNFD, the VNFM shall consider it valid in 
        case it is a valid JSON structure.

        NOTE: "Extensions" and "vnfConfigurableProperties" child attributes are always declared in the VNFD.
        
        If the VNF instance is in the "INSTANTIATED" state, the validation shall also include 
        ensuring the presence of all "extensions" and "vnfConfigurableProperties" child attributes that are 
        marked as "required" in the VNFD. 

        NOTE: This allows to build the set of "extensions" and "vnfConfigurableProperties" incrementally 
        prior VNF instantiation but ensures their completeness for an instantiated VNF instance.

        The absence of a metadata item that is marked "required" in the VNFD shall not be treated as an error.

        In case of an error during validation, the operation shall be automatically rolled back, and 
        appropriate error information shall be provided in the "VnfLcmOperationOccurrenceNotification" 
        message and the "VnfLcmOpOcc" data structure. 
        The processing of changes to the "metadata" / "extensions" / "vnfConfigurableProperties" attributes 
        shall be performed in the "PROCESSING" phase of the LCM operation. The change shall be atomic, i.e. the 
        result of intermediate stages shall not be visible in the API. In case of successful completion of the 
        processing and validation, the attributes shall be provided in the "VnfInstance" data structure and 
        the operation shall proceed towards successful completion.

        This method shall follow the provisions specified in the tables 5.4.7.3.1-1 and 5.4.7.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        The steps and conditions that apply as the result of successfully executing this method
        are specified in clause 5.4.1.2.
        In addition, once the VNFM has successfully completed the underlying VNF LCM operation occurrence,
        it shall set the "flavourId" attribute in the representation of the "Individual VNF instance"
        resource to the value of the "newFlavourId" attribute passed in the "ChangeVnfFlavourRequest"
        data in the POST request.

        When initiating a change of the current VNF flavour, the values of the extensions and/or VNF 
        configurable properties, can differ between the new flavour and the old flavour of the VNF instance.
        The VNFM shall apply the "extensions" and "vnfConfigurableProperties" attributes in the 
        "ChangeVnfFlavourRequest" data structure in the payload body to the existing "extensions" and 
        "vnfConfigurableProperties" attributes from the "VnfInstance" data structure according to the rules 
        of JSON Merge Patch (see IETF RFC 7396). The VNFM shall ensure that the content of the resulting 
        "extensions" and "vnfConfigurableProperties" attributes is valid against the VNFD (which includes 
        ensuring the presence of all child attributes that are marked as "required" in the VNFD). In case
        of an error, the operation shall be automatically rolled back, and appropriate error information 
        shall be provided in the "VnfLcmOperationOccurrenceNotification" message and the "VnfLcmOpOcc" data 
        structure. The processing of changes to the "extensions" / "vnfConfigurableProperties" attributes 
        shall be performed in the "STARTING" phase of the LCM operation. The change shall be atomic, i.e. 
        the result of intermediate stages shall not be visible in the API. In case of successful completion 
        of the processing and validation, the attributes shall be provided in the "VnfInstance" data structure 
        and the operation shall proceed to obtain the grant.

        The POST method initiates cancelling an ongoing VNF lifecycle operation while
        it is being executed or rolled back, i.e. the related "Individual VNF LCM operation occurrence"
        resource is either in "STARTING" or "PROCESSING" or "ROLLING_BACK" state.
        This method shall follow the provisions specified in the tables 5.4.17.3.1-1 and 5.4.17.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        Before returning the "202 Accepted" response, the VNFM shall update the "isCancelPending"
        and "cancelMode" attributes in the representation of the parent resource according to the
        provisions in clause 5.5.2.13.

        In case of success of processing the asynchronous request:
        1)	If the request has been processed in "STARTING" state, the "operationState" attribute
            in the representation of the parent resource shall be changed to "ROLLED_BACK".
        2)	If the request has been processed in "PROCESSING" or "ROLLING_BACK" state,
            the "operationState" attribute in the representation of the parent resource
            shall be changed to "FAILED_TEMP".

        In both cases, the VNFM shall update the "isCancelPending" and "cancelMode" attributes
        in the representation of the parent resource according to the provisions in clause 5.5.2.13
        to reflect the new status, and the applicable "result" notification according to clause 5.6.2.2
        shall be emitted to indicate that the execution of the underlying VNF LCM operation occurrence
        has temporarily failed.
        Due to race conditions, the processing of the actual operation that is to be cancelled may eventually
        still succeed, in which case the "operationState" attribute in the representation of the parent
        resource shall represent the result of that operation, rather than the result of the cancellation.

        The POST method creates a new subscription.
        This method shall follow the provisions specified in the tables 5.4.18.3.1-1 and 5.4.18.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        As the result of successfully executing this method, a new "Individual subscription"
        resource as defined in clause 5.4.3 shall have been created. This method shall not trigger any notification.
        Creation of two "Individual subscription" resources with the same callback URI and the same filter
        can result in performance degradation and will provide duplicates of notifications to the NFVO,
        and might make sense only in very rare use cases. Consequently, the VNFM may either allow creating
        an "Individual subscription" resource if another "Individual subscription" resource with the same
        filter and callback URI already exists (in which case it shall return the "201 Created" response code),
        or may decide to not create a duplicate "Individual subscription" resource (in which case it shall
        return a "303 See Other" response code referencing the existing "Individual subscription" resource
        with the same filter and callback URI).

        The POST method creates a new "Individual VNF snapshot" resource.

        As a result of successfully executing this method, a new "Individual VNF snapshot" 
        resource as defined in clause 5.4.24 shall have been created.

        The creation of an "Individual VNF snapshot" resource can be performed for two reasons:
        - To create an "Individual VNF snapshot" resources that can later be populated by a 
        new VNF snapshot taken from a VNF instance (refer to clause 5.4.21.3.1).
        - To create an "Individual VNF snapshot" resource that can be populated with information 
        gathered from a VNF snapshot package extraction. In this case, the API consumer indicates 
        the source of the VNF snapshot package in the payload body of the POST request to the 
        present resource.

        In the second case, for a successful execution of the operation, the values in the 
        "VnfSnapshotInfo" data structure representing the "Individual VNF snapshot" resource 
        shall be applied as follows:
        - If the request (refer to clause 5.5.2.20) includes the "vnfSnapshot" attribute, 
        the VNFM shall apply the "VnfSnapshotInfo" with such provided information.
        - If the request (refer to clause 5.5.2.20) does not include the "vnfSnapshot" 
        attribute, the VNFM shall first fetch the VNF snapshot record from the source VNF 
        snapshot package signalled by the "vnfSnapshotPkgId" attribute in the request and 
        then apply the "VnfSnapshotInfo" from the fetched VNF snapshot record.

        This method shall follow the provisions specified in the tables 5.4.23.3.1-1 
        and 5.4.23.3.1-2 for URI query parameters, request and response data structures,
