Code Issues Proposed changes

Use virt module to abort if vms are running

Browse Source 
Added check to call shutdown a second time, but at the same time
utilize the collected fact to help ensure that virtual machines
have been stopped

If the ansible module indicates that it had to send a shutdown
command after sixty seconds, then the upgrade is aborted and a
message is reported directing the user to shut down their virtual
machines and retry.
