2. If peer config already has a table, then not allow set this table's namespace to the peer config.

Set a exclude namespace in the peer config means that all tables in this namespace can't be replicated to the peer cluster.

1. If peer config already has a exclude namespace, then not allow set any exclude table of this namespace to the peer config.
2. If peer config already has a exclude table, then not allow set this table's namespace as a exclude namespace.
