Config files remain same, but the 'glusterfs' process itself can re-read the
config file from 3.1.x onwards where as in 3.0.x or earlier versions, it
could read the config file only once. Due to this, with glusterfs 3.1.x +
(ie, 3.2.x too), you can edit config files and make the process re-read it.
