Description

Based on the discussion in https://cwiki.apache.org/confluence/display/KAFKA/kafka+Detailed+Replication+Design+V3 , it's more efficient to communicate state change commands between the controller and the broker using a direct RPC than via ZK. This ticket will be implementing an admin RPC client for the controller to send state change commands.
