* plugin/rewrite: don't set or use ecs.DraftOption

Don't know why we are accessing this and explicitally setting it to
False (the default).
Any kill with fire - makes the build, build again.

* remove this

- Dnstap require protocol, address and port info about peer. So, I
   removed conversion of TCPAddr to IPAddr

* Use seconds for bucketing.
* Add template for high accuracy timing buckets to avoid copy-pasta.

Use caching, just ask etcd for every query. This also improves
throughput because the single lock in inflght is bypassed.

* ipv6 UT for endpoint

* tweak

Remove most 303 TTLs (those get skipped by the test) and use 5, which is
the default for all tests.

The TTL was still zero, instead it should adhere to the k.ttl setting.
Change this and update tests to match.

* clean up and add some ipv6 tests

* aaaa endpoint

* gofmt

* plugin/kubernetes: Add GetNamespaceByName

A bare or wildcard query for just the namespace should return NODATA,
not NXDOMAIN, otherwise we deny the entirety of the names under the
namespace.

Add test to check for this in pod verified mode.

* Review

More comments and move namespace code to namespace.go

* Update vendor directory for latest changes.

Add a note in about using the 'pinned' label for prevent stalebot from
closing your issue.

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

* plugin/log: remove need to specify stdout

Since log will only be output to stdout is doesn't make sense to
specify it in Corefile.

Fixes: #1218

* fixup! plugin/log: remove need to specify stdout

* use index for svc reverse lookup

* temp revert

* restore reverse.go

* restore reverse_test.go

* plugin/log: remove OutputFile

We use stdout for everything, remove OutputFile as it isn't used and
causes confusion.

Fixes #1216

* PR feedback

No need to have this build all the time.

Because we have our own mux we can't depend on the dns.Mux to do the
Question section checking for us. Clarify this in the comment.

I think this badge is misleading as we are not a library so the number of projects we are used in is not really relevant to our adoption. It is more-or-less just the number of external plugins people have built.

* fix pods disabled behavior

* do away with pod mode specific error

We are used by 10+ other projects now. Think it makes
sense to add this badge.

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

This fix is an attempt to fix the issue raised #1192.
The issue that a plain `dep -ensure update` fails is because
the incompatibility of ugorji/go with the rest of packages (etcd, k8s etc)
and the incompatibility of client-go vs. apimachinery.

This fix fixed apimachinery and ugorji/go so that it is possible
to use `dep -ensure update`.

Previously updates has to be done individually, e.g.,
`dep -ensure update github.com/coreos/etcd`

This fix fixes #1192.

While we at it, why not add a target for Windows as well.

This also introduces a VERBOSE option that defaults to -v, but it empty
when releases so that you can actually see what you're building.

Move an @echo out of shell snippet into the Makefile, as that errored
with @echo: command not found.
