CnosDB returns EAGAIN ("Tskv: Index: index storage error: Resource
temporarily unavailable (os error 11)") on DROP DATABASE under
SQLancer's DDL load (cnosdb/cnosdb#2435). The CI job has been red on
main for 14+ months, the only published image tags are rolling daily
builds (no LTS), and upstream development appears stalled. Pin and
retry attempts (#1341) did not help.
Remove the CnosDB provider, tests, CI job, and documentation entries.
Move CnosDB to the "Previously Supported DBMS" table in CONTRIBUTING.md.
