Public bug reported:

This was observed in the Juno release.

Because targeted live and cold migrations do not go through the
scheduler for policy-based decision making, a VM could be migrated to a
host that would violate the policy of the server-group.

If a VM belongs to a server group, the group policy will need to be checked in the compute manager at the time of migration to ensure that:
1. VMs in a server group with affinity rule can't be migrated.
2. VMs in a server group with anti-affinity rule don't move to a host that would violate the rule.
