> The KIP mentions a number of metrics which we should add, but haven't yet
> done so. IT would also be good to have tools to help diagnose degenerate
> situations like:
> # If a consumer is stuck, we should be able to find the LSO of the partition
> it is blocked on, and which producer is holding up the advancement of the LSO.
> # We should be able to force abort any inflight transaction to free up
> consumers
> # etc.
