* 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/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/k8s: remove dependence on global var
Remove the global coreDNSRecord that was used. Remove tests the
referenced that var. Cleanup the rest.
* Rename function as well
* fixes
Drop the interfaceAddr interfaces and just use a function. Cleanup
all fallout from that. Remove the use of global variables and cleanup
the tests a bit.
