    Adds a repoducer for post live migration fail

    Adds a regression test or repoducer for post live migration
    fail at destination, the possible casue can be fail to get
    instance network info or block device info

    changes:
    adds return server from _live_migrate in _integrated_helpers

    NOTE(auniyal): Differences
      * Replaced GlanceFixture with fake.stub_out_image_service in regression test, as GlanceFixture does not exist in Ussuri

    NOTE(auniyal): Differences from ussuri to train
      * integrated_helpers: Added self.api parameter while calling
        wait_for_state_change.
      * regression: imported mock module, as unitetest.mock is addted post
        train release.
        as _create_server is not present in train used
        _build_minimal_create_server instead to _create_server.
