    Add functional recreate test for bug 1852610

    It is possible to delete a source compute service which has
    pending migration-based allocations and servers in VERIFY_RESIZE
    status. Doing so deletes the compute service and compute node
    but orphans the source node resource provider along with its
    resource allocations held by the migration record while there
    is a pending resized server.

    This adds a simple cold migrate test which deletes the source
    compute service while the server is in VERIFY_RESIZE status and
    then tries to confirm the resize which fails.

    Conflicts:
          nova/tests/functional/integrated_helpers.py

    NOTE(mriedem): The conflict is due to not having change
    Iea283322124cb35fc0bc6d25f35548621e8c8c2f in Queens. As a result
    the helper methods are moved from ServerMovingTests to
    ProviderUsageBaseTestCase within test_servers.py.
