Public bug reported:
There is _live_migration_cleanup_flags method in compute's manager class which
should decide whether it's needed to make cleanup after live-migration is done
or not. It accepts 2 params, from doc:
:param block_migration: if true, it was a block migration
:param migrate_data: implementation specific data
The problem is that current compute's manager code is libvirt-specific.
It operates values in migrate_data dictionary that valid only for libvirt
driver implementation.
This doesn't cause any bug yet because other drivers doesn't implement cleanup
method at all.
When anyone decide to implement this live-migration starts to fail. There is no
valid ci job to verify that.
live_migration_cleanup_flags - should become hypervisor specific. and we
should move it from compute manager to drivers.
