      This task resource represents the "Scale NS" operation. The client can use this resource to request to scale a NS
      instance. Scaling an NS instance can be performed by explicitly adding/removing existing VNF instances to/from the
      NS instance, by leveraging on the abstraction mechanism provided by the NS scaling aspects and NS levels information
      elements declared in the NSD or by scaling individual VNF instances that are part of the NS itself. When adding VNFs
      and nested NSs - already existing or not - to the NS to be scaled, the NFVO shall follow the indications provided by the
      dependencies attribute, as specified in the corresponding NSD.
      
      In case the NS is a composite NS, it is also possible to scale directly its nested NS, as they are also NS
      and thus indirectly effectively scale the composite NS

    description: >
      This resource represents subscriptions. 
      The client can use this resource to subscribe to notifications related to NS
      lifecycle management, and to query its subscriptions.
    post:

        Subscribe

        The POST method creates a new subscription.
        This method shall support the URI query parameters, request and response data structures, and response codes, as
        specified in the Tables 6.4.16.3.1-1 and 6.4.16.3.1-2.
        Creation of two subscription resources with the same callbackURI and the same filter can result in performance
        degradation and will provide duplicates of notifications to the OSS, and might make sense only in very rare use cases.
        Consequently, the NFVO may either allow creating a subscription resource if another subscription resource with the
        same filter and callbackUri already exists (in which case it shall return the "201 Created" response code), or may decide
        to not create a duplicate subscription resource (in which case it shall return a "303 See Other" response code referencing
        the existing subscription resource with the same filter and callbackUri).
