"""Kingsoft Cloud (金山云) driver — archival tenant, no live sync.

PingCAP decommissioned 金山云 long ago; the only rows under this
provider type are the 541 servers + 13 LBs migrated from the legacy
CMDB (``vendor_id=1``). The driver registers the provider so the
cloud tenant filter can render "金山云 (历史)" as a real tenant, but
there is no test-connection, no config schema, and no capabilities —
writes always fail loudly.
