Description of problem:
The operation of attaching a cinder volume of a domain located in one datacenter to a VM located in a cluster that belongs a different datacenter should be blocked, as the current design supports one cinder domain per datacenter.
The VM is un-usable and every action that is attempted(except snapshot creation)
end with CDA message:
"Cannot run VM. Storage Domain doesn't exist"

Version-Release number of selected component (if applicable):
rhevm-3.6-14

How reproducible:
100%

Steps to Reproduce:
* have setup with two datacenters, one of them has cinder domain

1.create a VM on the cluster that belongs to the 'non-cinder datacenter'
2.create one floating cinder volume
3.attach the floating disk to the VM
4.attempt to run VM, create template etc.

Actual results:
The successful operation ends with un-usable VM that prompts CDA upon every action

Expected results:
This bug will handle the UX part of the bug ->
* disks from a different datacenter should not be offered at the pop up attach menu.

Will be opened as a separate bug
* the operation should be blocked from api
