Praefect configuration for database with no proxy
What does this MR do?
Praefect now requires a direct connection to the PostgreSQL instance. Before that we could use a single connection address despite if PgBouncer were used or not. As Praefect now would rely on the LISTEN/NOTIFY functionality of the PostgreSQL database it requires a direct connection (PgBouncer doesn't support it for 'transactional' connection management).
