IMPALA-8138: Reintroduce rpc debugging options

In the past, we had fault injection options for backend rpcs
implemented in ImpalaBackendClient. With the move the krpc, we lost
some of those options.

This patch reintroduces equivalent options, except that they now
utilize the existing DebugAction framework, which is more flexible and
powerful than the FAULT_INJECTION framework used previously.
