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.

* Reduce test line-count

* ....and fix test

* Drop use of append

* cosmetic changes

* that was a typo

* 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

Signed-off-by: Miek Gieben <miek@miek.nl>

* Set incoming object to nil

Explicataliy discard the converted object; we did a deep copy it's
not needed anymore.
