Review comment:
@mike-tutkowski, following @anshul1886 I changed this code to look for any
host in the zone that is of the same hypervisor type of the cluster where the
original volume of the snapshot resides on.
So, what do you guys think? let´s use only hosts of the cluster where the
volume of the snapshot has been taken resides on? For me, it seems an easy way
to cope with these different scenarios that we have.
