Good suggestion David. The only downside about this is since the config is at multiple level
the user hopefully shouldn't get confused figuring out the inheritance.

Also if disabled already created storage pools will still remain, only new storage pools won't

Maybe some level of inheritance? Perhaps the setting is at the host level, but you can turn
it on/off at the cluster/pod/zone and it inherits to all hosts within that given level.
