[pve-devel] [PATCH manager] Allow setting device class on osd create

[Alwin Antreich]

In some situations Ceph's auto-detection doesn't recognize the device
class correctly. The option allows to set it directly on osd create,
instead of altering it afterwards. This way the cluster doesn't need to
shift data back and forth unnecessarily.
