Description of problem:
Continuous triggers on the UpgradeBackupController on every z-upgrades caused out of space issues for some customers. We decided in a meeting to remove the (undocumented) z-stream upgrade triggers. In addition we're going to add a retention mechanism by deleting all files and folders in /etc/kubernetes/cluster-backup before taking a y-stream upgrade backup.
Version-Release number of selected component (if applicable):
4.10 -> 4.14
How reproducible:
always
Steps to Reproduce / expected results:
* do a z-upgrade * observe that no backup should be taken anymore * do a y-upgrade * observe that a backup is still taken * note that any previous backups should not exist anymore in /etc/kubernetes/cluster-backup
