Handles synchronization of access control list entries and updates throughout all nodes in the
cluster. The {@link AccessController} instance on the {@code _acl_} table regions, creates a
znode for each table as {@code /hbase/acl/tablename}, with the znode data containing a serialized
list of the permissions granted for the table. The {@code AccessController} instances on all
other cluster hosts watch the znodes for updates, which trigger updates in the
{@link AuthManager} permission cache.
