* For caddy v1 in our org
This RP changes all imports for caddyserver/caddy to coredns/caddy. This
is the v1 code of caddy.
For the coredns/caddy repo the following changes have been made:
* anything not needed by us is deleted
* all `telemetry` stuff is deleted
* all its import paths are also changed to point to coredns/caddy
* the v1 branch has been moved to the master branch
* a v1.1.0 tag has been added to signal the latest release

Abstract the caddy call and make it simpler.
See #3261 for some part of the discussion.
Go from:
~~~ go
func init() {
caddy.RegisterPlugin("any", caddy.Plugin{
ServerType: "dns",
Action: setup,
})
}

To:
~~~ go
func init() { plugin.Register("any", setup) }

This requires some external documents in coredns.io to be updated as
well; the old way still works, so it's backwards compatible.

* plugin/health: remove ability to poll other plugins
This mechanism defeats the purpose any plugin (mostly) caching can still
be alive, we can probably forward queries still. Don't poll plugins,
just tell the world we're up and running.
It was only actually used in kubernetes; and there specifically would
mean any network hiccup would NACK the entire server health.

Add a ready plugin that allows plugin to signal when they are ready.
Once a plugin is ready it is not queried again.
This uses same mechanism as the health plugin: each plugin needs to
implement an interface.
Implement readines for the *erratic* plugin to aid in testing.
Add README.md and tests moduled after the health plugin; which will be
relegated to just providing process health. In similar vein to health
this is a process wide setting.
With this Corefile:
~~~
. {
erratic
whoami
ready
}
bla {
erratic
whoami
}
~~~
ready will lead to:
~~~ sh
% curl localhost:8181/ready
% dig @localhost -p 1053 mx example.org
% curl localhost:8181/ready
OK%

*ready* can be used in multiple server blocks and will do the right
thing; query all those plugins from all server blocks for readiness.
This does a similar thing to the prometheus plugin.

* Fix EDNS0 compliance
Do SizeAndDo in the server (ScrubWriter) and remove all uses of this
from the plugins. Also *always* do it. This is to get into compliance
for https://dnsflagday.net/.
The pkg/edns0 now exports the EDNS0 options we understand; this is
exported to allow plugins add things there. The *rewrite* plugin used
this to add custom EDNS0 option codes that the server needs to
understand.
This also needs a new release of miekg/dns because it triggered a
race-condition that was basicly there forever.
See:
* https://github.com/miekg/dns/issues/857
* https://github.com/miekg/dns/pull/859
Running a test instance and pointing the https://ednscomp.isc.org/ednscomp
to it shows the tests are now fixed:

* server: actually scrub response
Did all the worked, hooked it up wrongly :(
This also needs test, but those are hard(er) because we only receive
packets after they have been decoded; i.e. we never see the wirefmt.
Signed-off-by: Miek Gieben <miek@miek.nl>
* Add tests
Add a test for checking is compression pointers are set in the packet.
This also adds an undocumented 'large' feature to the erratic plugin to
send large responses that should be compressed.
Commenting the Scrub out in server results in:
=== RUN TestCompressScrub
--- FAIL: TestCompressScrub (0.00s)
compression_scrub_test.go:41: Expected returned packet to be < 512, got 839
FAIL
exit status 1
FAIL github.com/coredns/coredns/test 0.036s
Actually checking the size might be easier, but lets be thorough here
and check the pointers them selves.

Add support for axfr. This to fix and test long standing axfr issues
that are hard to test if we don't support it directly in coredns.
The most intriguing feature is withholding the last SOA from a response
so the client needs to wait; drop (no reply) and delay is also
supported. All TTLs are set to zero.
Add simple tests that checks if first record is a SOA.

* Clean up tests logging
This cleans up the travis logs so you can see the failures better.
Older tests in tests/ would call log.SetOutput(ioutil.Discard) in
a haphazard way. This add log.Discard and put an `init` function in each
package's dir (no way to do this globally). The cleanup in tests/ is
clear.
All plugins also got this init function to have some uniformity and kill
any (future) logging there in the tests as well.
There is a one-off in pkg/healthcheck because that does log.

* global: move to context
Move from golang.org/x/net/context to std lib's context.
Change done with:

for i in **/*.go; do goimports -w $i; done
* drop from dns.pb.go as well
This should have everyone, but the process was quite manual. The rename
from middleware -> plugin also meant I had to do some extra digging on
who actually submitted the PR. I also double checked the current list of
people with commit access.
Every plugin now has an OWNERS, except *reverse*. I'll file a bug for
that.
* 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.
