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.
