    Description

      Though this is a broader and bigger change, it original motivation derives from HBASE-8751: the newly introduced per-peer tableCFs attribute should be treated the same way as the peer-state, which is a permanent sub-node under peer node but using permanent zk node is deemed as an incorrect practice. So let's refactor to eliminate the permanent zk node. And the HBASE-8751 can then align its newly introduced per-peer tableCFs attribute with this correct implementation theme.
