Added a library for daemon reload and fixing testcase

After changing the type of unit file from INFO
to DEBUG. Performing daemon reload. Earlier using
running commands continuosly to generated debug
messages instead of running continuosly, restarted
glusterd in one of the nodes so that while handshake
the logs will be in Debug mode. After validating
reverting back the unit file to INFO and daemon
reload
