Live Migrate instances in non-ACTIVE states
Currently only instances in ACTIVE states can be live-migrated. This blueprint proposes that we support other stable vm_states.
1. Bring all non-active instances to 'PAUSED' state. This will require shutoff instances to be started as PAUSED.
2. Migrate the instance and leave it at PAUSED state.
3. In post live-migration at destination, take the VM to the required state by using the vm_state as a hint.
