    API compare-and-swap updates based on revision_number

    Allows posting revision number matching in the If-Match header
    so updates/deletes will only be satisfied if the current revision
    number of the object matches.

    DocImpact: The Neutron API now supports conditional updates to resources
               that contain the standard 'revision_number' attribute by
               setting the revision_number in an HTTP If-Match header.
