Description

This'll be a little interesting because the MDS doesn't have local storage. Evaluate if feature sets are best stored in per-MDS data (i.e., a thing stuck in the log or similar) or in the MDSMap. We want to prevent, for instance, a new MDS turning on and putting data into omaps, and then getting replaced with an older version of the software that errors out in strange ways.
