Release Note

Support replication by namespaces config in peer.
1. Set a namespace in peer config means that all tables in this namespace will be replicated.
2. If the namespaces config is null, then the table-cfs config decide which table's edit can be replicated. If the table-cfs config is null, then the namespaces config decide which table's edit can be replicated.
3. If you already have set a namespace in the peer config, then you can't set any table of this namespace to the peer config. If you already have set a table in the peer config, then you can't set this table's namespace to the peer config.

Description

Now we only config table cfs in peer. But in our production cluster, there are a dozen of namespace and every namespace has dozens of tables. It was complicated to config all table cfs in peer. For some namespace, it need replication all tables to other slave cluster. It will be easy to config if we support replication by namespace. Suggestions and discussions are welcomed.
