Description
In database level feeds*, when a "table has been dropped" error occurs, remove that table from the frontier & checkpoint, persist them, and restart. When the feed comes back up it should not watch the dropped table.
* We may in the future consider exposing this behaviour as opt-in for regular changefeeds.
