Add KEP-5502 for EmptyDir volume sticky bit support

[oliverguenther]

This KEP proposes adding an optional stickyBit field to EmptyDirVolumeSource that sets directory permissions to 01777 instead of 0777, preventing users from deleting files they don't own.

Hi @oliverguenther. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
