        The POST method initiates rolling back a VNF lifecycle operation if that operation
        has experienced a temporary failure, i.e. the related "Individual VNF LCM operation occurrence"
        resource is in "FAILED_TEMP" state.
        In case of rolling back an occurrence of the "InstantiateVnf" operation, the VNFM shall
        request to the VIM the release of the virtualised resources that were allocated for the related VNF instance.
        The "rollback" task shall be supported by the VNFM for any VNF LCM operation occurrence that represents an
        "InstantiateVnf" operation in FAILED_TEMP state.
        This method shall follow the provisions specified in the tables 5.4.15.3.1-1 and 5.4.15.3.1-2
        for URI query parameters, request and response data structures, and response codes.
        In case of success of processing the asynchronous request, the "operationState" attribute
        in the representation of the parent resource shall be changed to "ROLLING_BACK" and the applicable
        "start" notification according to clause 5.6.2.2 shall be emitted to indicate that rollback of the
        underlying VNF LCM operation occurrence is attempted.

      description: |
        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.

        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
