Improve WAL-E alert for 'WALEBackupDelayed'
During our recent failover production#637 (closed), the alert WALEBackupDelayed
fired. This was technically a false alarm. Wal-E backups continued to work, the data that prometheus was looking at was correct, but fired when another server had begun processing uploads to S3.
Improve this alert to reduce alert fatigue during incidents. This alert introduced noise into an already stressful situation.
