Avi Kivity 7f1e368e92 Merge 'replica/database: drop_column_family(): properly cleanup stale querier cache entries' from Botond Dénes ...

Said method has to evict all querier cache entries, belonging to the to-be-dropped table. This is already the case, but there was a window where new entries could sneak in, causing a stale reference to the table to be de-referenced later when they are evicted due to TTL. This window is now closed, the entries are evicted after the method has waited for all ongoing operations on said table to stop.

Fixes: #10450

Closes #10451
