git commit: updated refs/heads/master to 450d890

Repository: cloudstack
Updated Branches:
  refs/heads/master 918c32043 -> 450d89094


CLOUDSTACK-6830: Fixed during VM migration, volumes on zone wide primary store
requires storage migration resulting in failure of VM migration. This also improves
the hostsformigration api. Firstly we were trying to list all hosts and then
finding suitable storage pools for all volumes and then we were checking whether
vm migration requires storage migration to that host. Now the process is updated.
We are checking for only those volumes which are not in zone wide primary store.
We are verifying by comparing volumes->poolid->clusterid to host clusterid. If it
uses local or clusterids are different then verifying whether host has suitable
storage pools for the volume of the vm to be migrated too.
