    Add version hashes to enforce version updates

    Nova uses a map of hashes for important parts of versioned objects. It
    keeps a static mapping of previous objects, and generates a map of the
    current objects. If these differ, a test fails, enforcing that the hash
    of the object needs to be updated. Along with this, it usually means
    that the version of the object itself needs to be updated because the
    RPC contract of that object is now broken.

    oslo_versionedobjects contains a fixture for helping generate and test
    these hashes, so this fixture is used to test Magnum's object hashes.
