[ANSIENG-4314] | Adding check sub property role for testing comma seperated list of values

[rrbadiani]

Description

In a couple of test cases we had a check to confirm the value of sasl.enabled.mechanisms is set to GSSAPI,PLAIN but it could also have been set to PLAIN,GSSAPI. so instead of doing a string matching of values we can parse the value and split by comma and make a list. Then compare items of list to ensure all the mechanisms which should be present are actually present.

This will help remove flakiness as at times this property would be set to GSSAPI,PLAIN and at other times it would be PLAIN,GSSAPI both of which are same from cp point of view.
