Set the replicable namespaces config for the specified peer.
1. The replicate_all flag need to be false when set the replicable namespaces.
2. Set a namespace in the peer config means that all tables in this namespace
will be replicated to the peer cluster. If peer config already has a table,
then not allow set this table's namespace to the peer config.
Examples:
# set namespaces config is null, then the table-cfs config decide
# which table to be replicated.
hbase> set_peer_namespaces '1', []
# set namespaces to be replicable for a peer.
# set a namespace in the peer config means that all tables in this
# namespace (with replication_scope != 0 ) will be replicated.
hbase> set_peer_namespaces '2', ["ns1", "ns2"]
