I've realized that moving an HE host to another DC/CL is not prevented, leading to an
awkward situation for which the host is UP in the new CL but still retains the
"silver crown". Moreover, "hosted-engine --vm-status" on another HE
host still show the departed host with score 0. The same situation can be achieved
removing an HE host that was previously set in Maintenance.
I think those operations should be prevented for HE hosts and a warning message like
"Please undeploy HE first" should be displayed. Otherwise trigger the HE
undeployment on host move/remove.
