Merge pull request #53466 from davidz627/localSSDUUID
Automatic merge from submit-queue. 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>. Add options for mounting SCSI or NVMe local SSD though Block or Filesystem and do all of that with UUID Fixes: #51431 Mount SCSI local SSD by UUID in /mnt/disks/by-uuid/, also allows for users to request and mount NVMe disks. Both types of disks will be accessable either through block or filesystem To see code in progress for NVMe and block support see working branch: https://github.com/davidz627/kubernetes/tree/localExt
