Problem:
    gluster command not found.
    
Cause:
    In Volinfo class we issue command 'gluster vol info' to perform
    operation like getting brick_root etc.
    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' to get path for gluster
    binaries.
