    Add functional recreate revert resize test for bug 1852610

    This builds on I644608b4e197ddea31c5f264adb492f2c8931f04 and
    adds a revert resize test which deletes the source compute service
    while the server is in VERIFY_RESIZE status and then reverts the
    resize. The results are a bit different from the confirm scenario
    because the confirm fails while the revert actually works which
    is more dumb luck based on where the compute service drops the
    move claim during the revert process (on the dest which still exists
    rather than the source).

    Conflicts:
          nova/tests/functional/integrated_helpers.py

    NOTE(mriedem): The conflict is due to not having change
    Iea283322124cb35fc0bc6d25f35548621e8c8c2f in Queens. As a result
    the _resize_and_check_allocations method is added to
    ProviderUsageBaseTestCase within test_servers.py.
