Review comment:
The fact that we have the high watermark in two places has always been
unsatisfying, but I have not prioritized coming up with a solution. I have been
inclined to say that `ReplicatedLog` owns the high watermark, so option 1 is
consistent with that. I might be tempted to leave that for a separate PR
though. In this case, since we are requesting a full truncation, it seems we
could just set the high watermark to the snapshot offset?
