This helps in selecting log level of the gluster gfapi, output to stderr.
The option is 'gluster_debug_level', can be tuned by editing
'/etc/libvirt/qemu.conf'
Debug levels ranges 0-9, with 9 being the most verbose, and 0 representing
no debugging output. The default is the same as it was before, which
is a level of 4. The current logging levels defined in the gluster
gfapi are:
0 - None
1 - Emergency
2 - Alert
3 - Critical
4 - Error
5 - Warning
6 - Notice
7 - Info
8 - Debug
9 - Trace
