geo-rep : fix gluster command path for non-root session

Problem:
gluster command not found.

Cause:
In Volinfo class we issue command 'gluster vol info' to get information
about volume like getting brick_root to perform various operation.
When geo-rep session is configured for non-root user Volinfo class
fails to issue gluster command due to unavailability of gluster
binary path for non-root user.

Solution:
Use config value 'slave-gluster-command-dir'/'gluster-command-dir' to get path
for gluster command based on caller.
