glusterd: rebalance support for cluster.rc framework

Issue:Rebalance is failing in cluster framework (any simulated cluster environment in same node ).
RCA:
  1. we are passing always "localhost" as volfile server for rebalance xlator .
  2. Rebalance daemons are overwriting  unix socket and log files each other.
     (All rebalance processes are creating socket with same name) .

Fix: set vol_file_server, unix socket and log files properly.
