> As discussed with Neha on the ML.
> It should be possible to configure a topic to disallow unclean leader election, thus
preventing the situation where committed messages can be discarded once a failed leader comes
back online in a situation where it was the only ISR.
> This would open kafka to additional usecases where the possibility of committted messages
being discarded is unacceptable.
