Fixes https://github.com/PostgREST/postgrest/issues/1512 Helps on environments where you can't send unix signals(Windows, managed containers). Also provides better UX for schema reloads - NOTIFY can be sent from pg clients(psql, pgadmin). `NOTIFY pgrst` - with no payload - should be done to reload the schema cache. Notifications with a payload will be ignored. The channel can be enabled with `db-channel-enabled`(false by default) and its name can be configured with `db-channel`. The LISTEN thread uses a dedicated pg connection. This connection is recovered if it fails. A debounce of 1ms is done in case too many NOTIFYs arrive.
