Merge pull request #38523 from MrHohn/kube-dns-rename

Automatic merge from submit-queue (batch tested with PRs 38058, 38523)

Renames kube-dns configure files from skydns* to kubedns*

`skydns-` prefix and `-rc` suffix are confusing and misleading. Renaming it to `kubedns` in existing yaml files and scripts.
