BUG-8402: Record modification failures

When a modification fails to apply, we must record the resulting
failure, as we have partially applied the state and hence should
never attempt to try to do it again even if the client retransmits
the request.

Furthermore we should stop responding to any subsequent requests
including reads, as our responses are not accurate anyway (and the
requests may have been enqueued before the client saw the failure).

Enqueue the failure and respond to all subsequent requests with it,
forcing the transaction to fail the canCommit() phase.
