glusterd: optimization of test cases

To reduce the overall time taken by the every regression job for all glusterd test cases,
avoiding some duplicate tests by clubbing similar test cases into one.

real time taken for all regression jobs of glusterd without this patch is 1959 seconds,
with this patch it is 1059 seconds.

Look at the below document for your reference.
