Subject: [PATCH 203/221] glusterd/shd: Change shd logfile to a unique name
With the shd mux changes, shd was havinga a logfile
with volname of the first started volume.
This was creating a lot confusion, as other volumes data
is also logging to a logfile which has a different vol name.
With this changes the logfile will be changed to a unique name
ie "/var/log/glusterfs/glustershd.log". This was the same
logfile name before the shd mux
