mon: disable min pg per osd warning

Now that the pg_autoscaler is on by default, it is "normal" (and okay) to
have a small number of PGs in the cluster if the overall cluster usage is
also low.  This setting just results in a health warning out of the box
when you create a pool and haven't written any data yet.
