Description

HBASE-16773 fixed a case where PriorityRpcServer handler threads are all occupied accessing hbase:acl table.

However, the fix relies on the fact that there is single region in hbase:acl table so that the access can be local.

As discussed at the end of HBASE-16773, we should disable split of hbase:acl table as well.
hbase:meta is normally much larger than hbase:acl table and it has only one region.
