Support Vm-HA across clusters in case of zone-wide scope primary storage #11807
Description
The required feature described as a wish
As a User/Admin/Operator
I would like to my HA enabled vm's to be restarted by vm ha across cluster in case the primary storage zone-scoped.
The current behaviour looks for hosts which are in Up state in the same cluster.
https://docs.cloudstack.apache.org/en/4.21.0.0/adminguide/reliability.html#ha-enabled-instances
As zone wide storage spans clusters it would be great the vm's gets started across cluster when a host goes down.

@kiranchavala
there are several changes for VM HA on zone-wide storage pool and VM migration across clusters
for example, #5164, and #4534, #7401, #8085
can you update the global configuration (or zone)
migrate.vm.across.clusterstotrue, and retry ?cc @NuxRo
