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.
This fix fixes 1464.

* plugin/kubernetes: smaller map
to continue with a theme: the map[string]bool can be reduced
to map[string]struct{} to reduce a tiny amount of memory.

* Import auth providers for K8s
* Vendor updates for K8s auth providers
* Remove Azure since it is not compiling
* Update vendor to remove Azure dependencies
* 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 a test to see if we copy the rcode correctly. Some minor cleanup in
import ordering and renaming NewUpstream to New as we already are in the
upstream package.
* 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
* update docs
* plugins: use plugin specific logging
Hooking up pkg/log also changed NewWithPlugin to just take a string
instead of a plugin.Handler as that is more flexible and for instance
the Root "plugin" doesn't implement it fully.
Same logging from the reload plugin:

* update docs
* better doc
* 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
Rename the constants to IP4arpa and IP6arpa (shorter and exported) and
make IsReverse return the type of the reverse zone which could be handy
for some callers.
Also add tests for IsReverse()
* plugin/kubernetes: axfr
Hook up dynamic SOA serial by setting ResourceEventHandlerFuncs in
dnsController.
Add prototype of returns msg.Services via the Transfer function. Leave
expanding this to RRs out of scope for a bit.
* plugin/kubernetes: axfr
Respond to AXFR queries
* Fixing race condition
* Fixing instantiation of dnstest writer
* Updates from review
* 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.
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
* plugin/kubernetes: wait until api is ready
Wait for HasSynced before allowing startup to avoid startup race.
Also do a small refactor in findServices() to pull a check out of the
loop - only needs to be done once.
* sigh
* 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
