mw/federation: add federation back as separate mw for k8s (#929) * 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

## Name
*federation* - enables federated queries to be resolved via the kubernetes plugin.
## Description
Enabling this plugin allows
[Federated](https://kubernetes.io/docs/tasks/federation/federation-service-discovery/) queries to be
Remove the word middleware (#1067) * 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

Enabling *federation* without also having *kubernetes* is a noop.

**NAME** will silently overwrite any previous value.
## Examples
Here we handle all service requests in the `prod` and `stage` federations.
