glusterd: Relocate rebalance sockfile
The defrag sockfile was moved from priv->workdir to DEFAULT_VAR_RUN_DIRECTORY. The format for the new path of the defrag sockfile is 'DEFAULT_VAR_RUN_DIRECTORY/gluster-rebalance-<vol-id>.sock'. This was needed because the earlier location didn't have a fixed length and could exceed UNIX_PATH_MAX characters. This could lead to the rebalance process failing to start as the socket file could not be created. Also, for keeping backward compatiblity, glusterd_rebalance_rpc_create will try both the new and old sockfile locations when attempting reconnection.
