    DRAFT - SOL003 - VNF Indicator interface
    IMPORTANT: Please note that this file might be not aligned to the current
    version of the ETSI Group Specification it refers to and has not been
    approved by the ETSI NFV ISG. In case of discrepancies the published ETSI
    Group Specification takes precedence.
    
    In clause 4.3.2 of ETSI GS NFV-SOL 003 v2.4.1, an attribute-based
    filtering mechanism is defined. This mechanism is currently not
    included in the corresponding OpenAPI design for this GS version. Changes
    to the attribute-based filtering mechanism are being considered in v2.5.1
    of this GS for inclusion in the corresponding future ETSI NFV OpenAPI
    design.

      description: >
        The POST method creates a new subscription.
        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 NFVO, and might make sense only in
        very rare use cases. Consequently, the VNFM 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).
