[Test]Add test to validate glusterd.info configuration file

1. Check for the presence of /var/lib/glusterd/glusterd.info file
2. Get the UUID of the current NODE
3. check the value of the uuid returned by executing the command
	"gluster system:: uuid get "
4. Check the uuid value shown by other node in the cluster
	for the same node "gluster peer status"
	on one node will give the UUID of the other node
