Bug Description

Reproduce steps:

1. boot instanceA with anti-affinity policy server group, instanceA start on hostA.
2. resize instanceA, instanceA was migrated to hostB, wait for verify resize.
3. boot instanceB with the same server group, the instanceB was scheduled to hostA because of anti-affinity policy.
4. resize-revert instanceA, the instanceA restart on the source host(hostA).
5. the instanceA and instanceB run on same host (hostA), the anti-affinity policy is broken.

When we setup the server group in booting instance logic, the source and destination hosts of resizing/migrating instance should been add into server group hosts in order to impact on the schedule of other instance with same server group.
