Update the file and dnssec docs and glarify what is implement and that
we only do NSEC.

Fix the code copied from Caddy to refer to Corefile and make 'coredns'
with flags pickup a local Corefile.

Also remove some references to Caddy in the docs and output of coredns.

Fixes #235

There is no good reason to be different than Caddy and allows us to
piggyback on it's documentation.

Adjust documentation for k8s and put contents of the k8sCorefile
in the README.md

See
https://github.com/mholt/caddy/commit/17709a7d3f1a6ee0c34bdb81c6332b1339ea7085
where there was a slight change (for the better) on how to register.

Fix the CoreDNS to adhire to this. Needs Caddy from master to compile at
this moment.

Fix "just push to master, because I know better" compilation error.

The will prolly make automatic releases easier.

Set version and name of the program. And then call coremain.Run().

The coremain split makes CoreDNS embeddable.

Also see #189 for an old PR.

Remove miek.nl in favor of example.org and other smaller cleanups.

Use the package go/ast/astutil for adding CoreDNS to caddy and removing
the http server stuff from it as well - we're only a DNS server, no need
to caddy all the HTTP stuff as well.

Results in smaller binary and plugin_generate.go being much smaller as
well.

This needs a patch in caddy to work properly, but we want something like
it anyway.

See https://github.com/mholt/caddy/pull/1058

* Set version to 001
* Remove k8stest, test fails is k8s is not there: touch luck
* Remove server directory: not used anymore
* Disable k8s test (for now)
* gometalinter changes

* Make CoreDNS a server type plugin for Caddy

Remove code we don't need and port all middleware over. Fix all tests
and rework the documentation.

Also make `go generate` build a caddy binary which we then copy into
our directory. This means `go build`-builds remain working as-is.

And new etc instances in each etcd test for better isolation.
Fix more tests and rework test.Server with the newer support Caddy offers.

Fix Makefile to support new mode of operation.

It is not middleware, so move it up one level. It was also use from
core/ showing that indeed its use is not limited to middlewares.

* Adding pod setup to kubernetes startup scripts

* Adding template description to k8s README.md

* Fix typo.

* Moving kubernetes setup scripts out of go folder

* Fixing script error
