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/wsgi/test_services.py NOTE(mriedem): The conflict is due to change If32bca070185937ef83f689b7163d965a89ec10a which is not in Stein.
