api: osd: destroy: remove mclock max iops settings

Ceph does a quick benchmark when creating a new OSD and stores the
osd_mclock_max_capacity_iops_{ssd,hdd} settings in the config DB.

When destroying the OSD, Ceph does not automatically remove these
settings. Keeping them can be problematic if a new OSD with potentially
more performance is added and ends up getting the same OSD ID.

Therefore, we remove these settings ourselves when destroying an OSD.
Removing both variants, hdd and ssd should be fine, as the MON does not
complain if the setting does not exist.
