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.
