MTV-1573 | Allow scheduler to migrate VMs with more disks

Issue: When migrating the VM using the warm migration with more disks than the MAX_VM_INFLIGHT the VM won't get scheduled and won't start the migration. Fix: Once the scheduler is empty the controller will start the migration of the large VMs. Signed-off-by: Martin Necas <[email protected]>
