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

* Adding messages to k8s scripts for clarity

Changes large parts of proxy lookup mechanism.

The duplicate zone checking erroneous added a nameserver for each
zone we are auth. for, creating to many backend hosts. So even when a
host was determined do be Down() we still got an (identical) new one
from the list.

The Down() and failure checking for upstream hosts had data race in the
uh.Fails check - we now use atomic.LoadInt32 for that.

Use and debug the test/server.go test servers implementation in the
TestStubLookup test to prevent going out to the internet.

Also delete the stub cycle test. That test was wrong and did not test
what it needed to be testing.  Deleted for now.

* Authoritative Answer - DNSKEY

* Improve Style

Add warning about in memory keys and the impossibilty to extract them.

* Adding parsing for label selector to Corefile

* Updating comment typo in k8sCorefile

* Adding implementation of label support to filter exposed objects

* Updating TODO list

* Always continue

* debug queries: more sane impl

This PR just add a msg.Service to debug instead of crafting an TXT RR
at that point. This way we lift on the normal way of generating debug
responses and don't muck with that implementation.

The tags=etcd is flaky as hell for some reason.

This PR adds debug support for failed lookups. I.e. when a record
is outside the configured domain, we do a forward lookup. If this
fails the error is silently dropped. This PR adds it back as an error
in when debugging is enabled.

Fixes #197

Make the receiver a pointer so that the uptdateStubZones map update will
retain the stubzones found, unlike the current case where the update
will be applied and then promptly forgotten, because it is working on a
copy.

Add test/etcd_test.go to test a large part of the code. This didn't
catch the chaos middleware hack though. The chaos middleware zones are
now *not* automatically added. You have to take care of that by yourself
(docs updates).

When using debug queries and falling through to the next middleware in
etcd, restore the original (with o-o.debug) query before passing it on.

* Removing old unused inline k8s API code and tests.
* Adding parsing implementation for `resyncperiod` keyword from Corefile.

* Enable docker (requires VM environment and sudo)
* Run kubernetes integration tests in Travis

Adding test cases for Corefile parsing.
Some code refactoring to allow test reuse.

* Updating comment to remove references to Caddy

* Updating documentation for k8s tests

* Avoid downloading kubectl if already exists

* Adding debug statement when namespace is not exposed.

* Adding basic kubernetes integration tests

* Makefile now contains a "testk8s" target. This target requires k8s to
  be running.
* Adding test/kubernetes_test.go file with a couple of basic A record
  tests.

* Updating k8s integration tests to only run k8s integration tests

* Adding support for namespace wildcards

* Refactoring to move filtering logic to kubernetes.go file

 Filtering now handled in kubernetes.go

* Adding wildcard test cases

* Adding skydns startup script. (To allow side by side testing of wildcards.)
* Commenting out record name assmebly based on NameTemplate. Need to improve template before this makes sense.

* Adding basic SRV integration tests

* Need to add verification for additional answer section

* Fixing comments and formatting

* Travis test execution appears to be failing on access to these
 constants

Travis breakage is due to "Infoblox-CTO" in src path
