As Azure doesn't allow "/" in label keys, we used to convert "/" to
"", but we didn't convert back "" to "/" in kops-controller. This
commit fixes this.

Change the conversion semantics so that "/" is converted to "s". ""
is converted to "__" so that we can distinguish the original "_" and
"_s".

Hi @kenji-cloudnatix. 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/test-infra repository.

As Azure doesn't allow "/" in label keys, we used to convert "/" to
"_", but we didn't convert back "_" to "/" in kops-controller.

Change the code to store a label key in a tag value so that we don't
need to worry about escaping.
