This fix deprecates endpoints for out-of-cluster k8s api,
The Corefile still takes multiple endpoints though only
the first one is used. A warning is shown if there are
multiple endpoints.

* Default to upstream to self
This is a backwards incompatible change.
This is a massive (cleanup) PR where we default to resolving external
names by the coredns process itself, instead of directly forwarding them
to some upstream.
This ignores any arguments `upstream` may have had and makes it depend
on proxy/forward configuration in the Corefile. This allows resolved
upstream names to be cached and we have better healthchecking of the
upstreams. It also means there is only one way to resolve names, by
either using the proxy or forward plugin.
The proxy/forward lookup.go functions have been removed. This also
lessen the dependency on proxy, meaning deprecating proxy will become
easier. Some tests have been removed as well, or moved to the top-level
test directory as they now require a full coredns process instead of
just the plugin.
For the etcd plugin, the entire StubZone resolving is *dropped*! This
was a hacky (but working) solution to say the least. If someone cares
deeply it can be brought back (maybe)?
The pkg/upstream is now very small and almost does nothing. Also the
New() function was changed to return a pointer to upstream.Upstream. It
also returns only one parameter, so any stragglers using it will
encounter a compile error.
All documentation has been adapted. This affected the following plugins:
* etcd
* file
* auto
* secondary
* federation
* template
* route53
A followup PR will make any upstream directives with arguments an error,
right now they are ignored.

This fix will error out when multiple https endpoints are specified,
as additional work is needed to support beyond http.

* Add support for authentication with kubeconfig files
* Update k8s plugin documentation
* Fix whitespace in README and tests
* Use clientcmd package to load kubeconfig file

* ADD: ignoreemptyservice option for kubernetes plugin
* Modify documentation and rename option to add space
* UPD: Add unit tests
* UPD: gofmt
* Add unit test for ignore emptyservice
* gofmt
* xfr tests failed
* Rename emptyservice to empty_service

* plugins: Return error for multiple use of some
Return plugin.ErrOnce when a plugin that doesn't support it, is called
mutliple times.
This now adds it for: cache, dnssec, errors, forward, hosts, nsid.
And changes it slightly in kubernetes, pprof, reload, root.
* more tests

* add noendpoints option
* go fmt

* add upstream @self and loop count
* 1st round of feedback
* allow argless upstream
* update test
* readmes
* feedback

Let caddyfile parser give us the token, the comma sep thing also didn't
work.
Fixes #1446

These can be just vars. Think that was intended as well.

* Simplify plugin/pkg/fall
* Remove unused import
* Fix fall_test
* Get fall coverage to 100% just because
* gofmt. sigh.

* Add pkg/fall for Fallthrough
Move this into it's own package to facilitate tests. Important bug
was fixed: make the names fully qualified.
Add fall package to hosts, reverse, etcd, and fix kubernetes and any
tests. The k8s tests are still as-is, might need a future cleanup.
|
|
* Add zone filtering to fallthrough
* Doh. gofmt
* Update documentation
|
|
Change to use a new 'endpoints' directive and use a constant
Add initial docs for 'endpoints' directive
Add tests to Kubernetes setup for endpoints
Changes based on PR feedback
endpoint_pod_names is a boolean config option. Chahanged docs to reflect this.
Add a test when endpoints_pod_names is not set
Update README.md
Remove endpointNameModeName as it is no longer used

* vendor
* code

|
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
