        Subscribe.
        The POST 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 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
        a new "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).
        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.
