> We currently have nodetool commands to invalidate certain caches like KeyCache, RowCache
and CounterCache. 
> Being able to invalidate auth caches as well can come in handy in situations where, critical
backend auth changes may need to be in effect right away for all the connections, especially
in configurations where cache validity is chosen to be for a longer duration. An example can
be that an authenticated user "User1" is no longer authorized to access a table resource "table1"
and it is vital that this change is reflected right away, without having to wait for cache
expiry/refresh to trigger.
