On the OSD side I kept the bluestore cache settings around just in case
folks wanted to disable autotuning and force a manual configuration. I
wouldn't be surprised if we eventually take them out though once the
double-cache avoidance PR merges (after sharding) followed by cache
age-binning. I'm hoping that will resolve any remaining reasons to do
manual tuning.
On the MDS side I'm not sure there's much reason to keep the old
settings, though I'll defer to Patrick. If we do keep the old settings
let's try to keep the conventions the same across daemons.

do either/both in one release if we make the mon translate/create the
