For zone files with more than 10,000 records, the goroutines and memory
pinned by dns.ParseZone won't be released unless the tokens chan is
drained. As Parse is called by (*Zone).Reload very frequently, this
causes memory leaks and OOM conditions.

* 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.

Update Caddy to v0.10.13 so that environment variables may be used after
Go template (e.g. in template's answer). v0.11.0 has been released, but
v0.10.13 is a smaller set of changes and has the necessary fix.
