> Removing a user from a group isn't reflected in getGroups even after a refresh. The following
sequence fails in step 7. 
> 1) add test_user to a machine with group1 
> 2) add test_user to group2 on the machine 
> 3) yarn rmadmin -refreshUserToGroupsMappings (expected to refresh user to group mappings)

> 4) yarn rmadmin -getGroups test_user (and ensure that user is in group2) 
> 5) remove user from group2 on the machine 
> 6) yarn rmadmin -refreshUserToGroupsMappings (expected to refresh user to group mappings)

> 7) yarn rmadmin -getGroups test_user (and ensure that user NOT in group2)
