This was added, but didn't see any use. For a large, complex chunk of
code we should have some users of it.
Remove all watch functionally from plugins, servers and packages.
Fixes: #2548

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.

This fix will error out when multiple https endpoints are specified,
as additional work is needed to support beyond http.
This fix fixes 1464.

* Add support for authentication with kubeconfig files
* Update k8s plugin documentation
* Fix whitespace in README and tests
* Use clientcmd package to load kubeconfig file
Create plugin/pkg/transport that holds the transport related functions.
This needed to be a new pkg to prevent cyclic import errors.
This cleans up a bunch of duplicated code in core/dnsserver that also
tried to parse a transport (now all done in transport.Parse).

Prevent future; "remove trailing whitespace" PR, but adding a simple
presubmit that checks for this.
This presubmit flagged quite some offenders, remove all trailing
whitespace from. Apart from that there aren't any other changes.

This PR documents the trick exposed in coredns/coredns#1357 about using wildcards to get all POD IPs from a service with ClusterIP (as used in 'endpoints')
* 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
Remove `fallthrough` from the federation example in the README. `fallthrough` isn't needed here and has no effect (federation has an implicit fallthrough for non-federated queries).
It's inclusion is confusing.
* Add manual pages
Generate manual pages from the README and extend README with Name and
Description sections.
The generation requires 'ronn' which may not be available. Just check in
all generated manual pages.
Implement health.Healther in erratic and kubernetes plugin. The
kubernetes' healtcheck is only performed on startup - i.e. turn
healthy after the initial loading.
Erratic follow the drop count: every query%drop turns the healthcheck
unhealthy.
Fixes: #985
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
Fix typo in kubernetes/README.md and remove DEV-README.md as it is stale
and information on the website is more up to date.
Remove large sections of text in plugin.md; just talk about how to
structure your plugin and docs.
* core: allow all CIDR ranges in zone specifications
Allow (e.g.) a v4 reverse on a /17. If a zone is specified in such a
way a FilterFunc is set in the config. This filter is checked against
incoming queries.
For all other queries this adds a 'x != nil' check which will not impact
performace too much. Benchmark function is added as well to check for
this as wel.
Add multiple tests in tests/server_reverse_test.go.
Benchmark shows in the non-reverse case this hardly impact the speed:

* README.md updates
* doc update
Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.
* Cant use spefic addr in test
* 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
