* 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
Add integration test with erratic. For this erratic now also returns an
autopath searchpath. This tests the whole chain; i.e registring a
searchfunction and calling that from autopath.
This tests does a autopathing domain and a non-autopathing one.
* middleware/authpath: Fix return from k8s mw
Return the correct search path from the kubernetes' AutoPath function.
Based on preliminary discussion in #870
* PodWithIP can be private
Fix and add docs to functions.
* CR: remove the error from AutoPathFunc
