Review comment:
Perhaps a log message here to say that the test caught an IOException as
expected by the test case.

> If the applyTransaction fails in the containerStateMachine, then the
> container should not accept new writes on restart,.
> This can occur if
> # chunk write applyTransaction fails
> # container state update to UNHEALTHY also fails
> # Ratis snapshot is taken
> # Node restarts
> # container accepts new transactions
