If an OSD is removed during the wrong conditions, it could lead to
blocked IO or worst case data loss.
Check against global flags that limit the capabilities of Ceph to heal
itself (norebalance, norecover, noout) and if there are degraded
objects.

Those are the things to check for that came to mind. If someone thinks
that we should definitely check for more, I am happy to send a v2.
I am also open to suggestions on how to phrase the warnings better.
I opted for separate hints to be able to show detailed hints so the
users have an idea how to act on the warning and to keep the logic
behind them simple.
