The steps in the tests:

• create a cluster with kv-query, kv, index, index with index quota as 256MB
• Create multiple indexes
• perform kv mutations till dgm is achieved
• Once dgm is achieved, increase the mem quota to 456M

We see 101% for resident ratio of employeebd12fabcc4664a10a2b177378a3734a6join_yr
