> HBASE-8751 introduces the tables/table-column families config for a replication peer.
It's very flexible for practical replication in hbase clusters.
> But it is easy to make mistakes during add or remove a table/table-column family for
a existing peer, especially when the table-cfs is very long, for we need to copy the current
table-cfs of the peer first,  and then add or remove a table/table-column family to/from the
table-cfs, at last set  back the table-cfs using the cmd: set_peer_tableCFs. 
> So we implements two new cmds: append_peer_tableCFs and remove_peer_tableCFs to do the
operation of adding and removing a table/table-column family. They are useful operation tools.
