d7cdb992b4 Measure and expose DNS programming latency from Kubernetes plugin. (#3171)
For now metric is measure only for headless services. Informer has been slighlty
refactored, so the code can measure latency without storing extra fields on
Endpoint struct.

plugin/kubernetes: skip deleting pods (#2853)
Don't add pods to our internal cache that are being deleted. This saves
a field in the struct as well.

Add (extra) comments about adding fields to the
object/{Pod,Service,Endpoint} structs.

plugin/kubernetes: add memory usage guidelines (#2424)
Add words in object.go on the memory use and put some future ideas in
there to use even less (if we have to at some point).

Add new plugin: external - resolve k8s ingress and LB address with external names (#2379)
* Add new plugin: external

This plugin works in conjunction with the kubernetes plugin and exports
ingress and LB addresses as DNS records. It bypasses backend.go and
backend_lookup.go flow because it is not needed.

README, tests are implemented. The tests only exercise the unit tests,
this has not been tested in any ci.

plugin/kubernetes: allow trimming down of cached items. (#2128)
* Convert to runtime.Object to smaller structs

This adds conversion for all the objects we want to keep in the cache.
It keeps the minimum for CoreDNS to function and throws away the rest.

The conversion:
api.Endpoints -> object.Endpoints
api.Pod       -> object.Pod
api.Serivce   -> object.Service

We needed to copy some client-go stuff to insert a conversion function
into NewIndexInformers.

Some unrelated cleanups in the watch functionality as that needed to be
touched because of the above translation of objects.

We can't really use len() here because we don't know the number before
