      summary: Create a new subscription to VNF indicator change notifications
      description: |
        This method creates a new subscription. As the result of successfully executing this method, a new "Individual
        subscription" resource as defined in clause 8.4.6 shall have been created.  This method shall not trigger any
        notification. Creation of two "Individual subscription" resources with the same callbackURI and the same filter
        can result in performance degradation and will provide duplicates of notifications to the VNFM, and might make
        sense only in very rare use cases. Consequently, the API producer may either allow creating a new "Individual
        subscription" resource if another "Individual 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
        "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 callbackUri). This method shall follow
        the provisions specified in the tables 8.4.5.3.1-1 and 8.4.5.3.1-2 for URI query parameters, request and response
        data structures, and response codes
