glusto-tests/glusterd: enable glusterd in debug mode
In this test case we will enable glusterd in debug mode and check the glusterd log for the debug messages. Steps followed: 1. Stop glusterd. 2. Change log level to DEBUG in /usr/local/lib/systemd/system/glusterd.service. 3. Remove glusterd log. 4. Start glusterd. 5. Issue some gluster commands. 6. Check for debug messages in glusterd log.
