      Description

      In namespaces and acls, zk callbacks are used so all participating servers are notified when there is a change in acls/namespaces list.

      The new visibility tags feature coming in copies the same model of using zk with listeners for the features' particular notifications.

      Three systems each w/ their own implementation of the notifications all using zk w/ their own feature-specific watchers.

      Should probably unify.

      Do we have to go via zk? Seems like all want to be notified when an hbase table is updated. Could we tell servers directly rather than go via zk?
