	* 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
