Force disconnect primary/replica dbs separately
What does this MR do?
Related issue: #333849 (closed)
The application periodically disconnects from the database to ensure existing connections are relatively balanced across a pool of pgbouncers. However, these frequent disconnects can lead to a much large number of connections being opened than would otherwise be expected.
Since the periodic disconnection behavior is more urgently needed on GitLab.com for the primary database, add a new setting that allows the disconnect interval to be set independently for primary and replica database connections.
