    objects: exclude revision_number from updatable fields

    Revision service plugin is the entity that updates the database model
    attribute, and we don't allow to modify the attribute on API layer. We
    should not allow to explicitly update it on OVO layer either.

    This can help with spurious unit test failures that sometimes try to
    update revision number and then reuse the same number to fetch the
    object. If revision service plugin decides to bump the number during the
    test case execution once more, using the old number may yield no
    results.
