Add Ceph OSD status and boot drive detection

New features:
- Added STATUS column showing Ceph OSD up/down and in/out status
  Format: "up/in", "up/out", "down/in", etc.
- Added USAGE column to identify boot drives and mount points
  Shows "BOOT" for root filesystem, mount point for others, "-" for OSDs
- Improved table layout with all relevant drive information

Now you can see at a glance:
- Which drives are boot drives
- Which OSDs are up and in the cluster
- Any problematic OSDs that are down or out
