Automatic merge from submit-queue (batch tested with PRs 57399, 57751, 57475). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. iscsi: set node.startup to manual If the default iSCSI node.startup is set to automatic, if there is a node failure, any pods on that node will get rescheduled to another node. If the failed node is later brought back up it will then try to log back in to any iSCSI sessions it had prior to the failure, which may no longer exist or may be now in-use by the other nodes. It appears most platforms keep the open-iscsi default of node.startup-automatic. But in case this system-wide setting has been changed, and just to be explicit, this sets node.startup values for kubernetes controlled volumes to manual. Fixes #21305 ```release-note iSCSI sessions managed by kubernetes will now explicitly set startup.mode to 'manual' to prevent automatic login after node failure recovery. This is the default open-iscsi mode, so this change will only impact users who have changed their startup.mode to be 'automatic' in /etc/iscsi/iscsid.conf. ```
