Description
If two file systems use the same data pool with different RADOS namespaces, it is necessary for them to cooperate on snapid increments.
I think this could be done with a shared RADOS object storing a counter?

Now that pg_autoscaler exists with pg merging, this feature is not compelling. Using separate pools for multifs has always been more attractive from an accounting perspective. Now pools are cheap to make and use so let's just do that.
