Evacuate each instance from the host (in the case of irrecoverable data loss) to another host

Registered by Aarti Kriplani

In case of irrecoverable data loss on host, all the instances on a host need to be rebuilt on another host.
Evacuate instance is already in place. It would make admin's life simple if there is a wrapper that would just evacuate all instances of the entire downed host to other hosts.
