client-go is a "empty interface" waste-land and we're missing an
integration test so we didn't catch. Try this.

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.
Updates miekg/dns#786
* 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
hand.

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.
Fixes#2153
* Configurable zone reload interval in file plugin
* passing reload config from auto plugin to file plugin. removed noReload property from Zone struct. fixed tests based on short file reload hack
* Add support for authentication with kubeconfig files
* Update k8s plugin documentation
* Fix whitespace in README and tests
* Use clientcmd package to load kubeconfig file
This is indeed (as Chris said) too spammy; disable the ping back of the
results for now - and rethink it a bit.
