* mw/kubernetes: resync to opts
Only used to initialize the cache that already has a dnsControlopts, so
remove it from the main kubernetes struct.
* Fix test
* mw/kubernetes: LabelSelector to options as well
Labels select is also only used for init. Don't carry it in the main
kubernetes struct.
* remove this test: can't happen
Caddyfile parser will only call setup when it sees kubernetes.
* erge gone wrong
