Update the database timeouts to higher values to prevent the services from disconnecting too frequently: - set the Galera HAProxy timeout to 90 minutes (with parameter) - set the database_idle_timeout to 5000 seconds (83 minutes) to allow the services to drop the connection before HAProxy does - add `on-marked-down shutdown-sessions` to Galera HAProxy balancer members to allow shutting down sessions when a Galera host goes down.
