mgr: override OSD hostname with CRUSH physical host in all metadata paths

mgr: override OSD hostname with CRUSH physical host in all metadata paths

In containerized deployments (e.g. Rook), OSD daemons report the
pod/container hostname. The CRUSH map records the physical host.
This mismatch causes 'ceph device ls' to show pod names instead of
physical hosts, breaking host-based device correlation.

Fix by deriving the CRUSH host bucket name for each OSD and substituting
it as the canonical hostname in all three metadata paths:
- MetadataUpdate::finish (async mon metadata fetch, primary path)
- Mgr::load_all_metadata OSD bulk-load (startup/failover)
- DaemonServer::fetch_missing_metadata (via MetadataUpdate)

The override is a no-op when the OSD is absent from CRUSH or when the
OSD map is not yet available.
