Description

Currently, many handlers perform a delegate null check, retrieve an operation interface from the delegate when non-null, and then perform a null check for the operation. When any of the checks returns null, we return a cassandraServiceUnavailable exception. We can simplify the checks by providing a utility method that all handlers can reuse.
