    Description

      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
