Router Federation Rename
-------
Enable Router to rename across namespaces. Currently the router federation rename is implemented by distcp. We must set the rpc timeout high enough so it won't timeout.
Enable Router to rename across namespaces. Currently it is implemented based on [HDFS Federation Balance](../../../hadoop-federation-balance/HDFSFederationBalance.md) and has some limits comparing with normal rename.
1. It is much slower than the normal rename so need a longer RPC timeout configuration. See `ipc.client.rpc-timeout.ms` and its description for more information about RPC timeout.
2. It doesn't support snapshot path.
3. It doesn't support to rename path with multiple destinations.
