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.

Suggestions from code review
Co-Authored-By: Chris O'Haver <cohaver@infoblox.com>
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.

* 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.

* re-introduce append here
We can't really use len() here because we don't know the number before
hand.

* Make the timestamp a bool; thats where it is used for

* Set incoming object to nil
Explicataliy discard the converted object; we did a deep copy it's
not needed anymore.
