* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
* 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
* mw/federaration
This PR add the federation back as a middleware to keep it more
contained from the main kubernetes code.
It also makes parseRequest less import and pushes this functionlity down
in the k.Entries. This minimizes (or tries to) the importance for the
qtype in the query. In the end the qtype checking should only happen
in ServeDNS - but for k8s this might proof difficult.
Numerous other cleanup in code and kubernetes tests.
* up test coverage
* mw/kubernetes: reverse zone in ZONE stanza not parsed
Properly parse the reverse zone syntax in the ZONES stanza as promised
in the README.
As short test case to test.
* add test
