This fix tries to address the issue raised in 1275 to clarify
the syntax for multiple endpoints specification.
This fix also adds additional test cases to demo the usage.

When we failing the healthcheck we should increate the fails for this
host; which is the *bleeping* point of doing the HC in the first place.
Add the missing atomic.Adds.
Fixes#1247
HC for google_https does not work because it does not HC the correct
set of IPs. Hard to solve in the current code - rather use forward as
the new impl. and leave this as legacy.
Remove superfluous println that we are refreshing the dns.google.com IP
address.
* 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
* 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
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
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
Add a dynamic SOA record (at least the serial and minttl). This create
another interface that should be implemented by the backends.
For now default to returning epoch in as a uint32 (no change from
before).
Lower the minTTL returned to 30s (from 60s)
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.
* readme: more tests
Add dnssec and file plugin to the test readme. This requires creating a
bunch of files with the right content. Doing so already unconvered an
unconditional type assertion in DNSSEC. This PR will include the fix for
that as well.
Also extended the snippets in the file plugin README, so that they are
whole Corefile - showing more value and checking all corefile snippets.
Create outliner right now is the kubernetes plugin, because even setting
the right env vars will result in:
open /var/run/secrets/kubernetes.io/serviceaccount/token: no such file or directory":
Which we can't create for a test.
* lint
Some cleanup in proxy and dnstap:
* just use time pkg directly and side step the indirection for Epoch
* Use Set in SetQueryEpoch to be more Go like. (Looked like a reader)
* Don't maintain two sets of time, we already track start, so use that.
* Use time.Time and convert when needed
* dedent the toDnstap function and put in a separate file
* 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
* 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
We support ENV variables in config files, add an example in the one for
metric, note that `localhost:` is a valid host (in Go), so the
TestReadme will parse this correctly.
Fixes#1150
* plugin/autopath: Add namespace selector and metrics
Add a namespace, so autopathing only is performed in this namespace.
This will make caching work for the cluster again.
Also export metrics that we've done a successful autopath
* dont shadow
* Fix
* Back the namespacing changes
