mention auto in reload docs

I just noticed this discrepancy in one of the `except` examples.

making response rewrites more prominent

This was just tagged and has the worker patch that improves performance.

Copy the OWNERS file from proxy and add rdrozhdzh to it.

Remove panic/recover and also use pkg/log to print the error. This
brings some consistency into the logging.

Fixes #1776

This enables CorBot to help with issues and PRs. See
github.com/miekg/dreck for the implementation and README (a bit sparse).

- review BUG related doc for Health and Premotheus after change of behavior to be compatible with reload feature. (#1790)

* plugin/forward: expose TLSConfig and error messages to public

* Add IsTLS() instead of TLSConfig()

* request.Match check Response bit as well

We should check this bit and reject them as invalid.

* Fix test

This allocates memory because of the append, just unroll the loop.
Also add benchmark.

Before:
goos: linux
goarch: amd64
pkg: github.com/coredns/coredns/plugin/cache
BenchmarkCacheResponse-4   	  100000	     11910 ns/op
BenchmarkMinMsgTTL-4       	 1000000	      1494 ns/op
PASS

After:
goos: linux
goarch: amd64
pkg: github.com/coredns/coredns/plugin/cache
BenchmarkCacheResponse-4   	  100000	     12016 ns/op
BenchmarkMinMsgTTL-4       	 2000000	       668 ns/op
PASS

These are not stored with newItem so we don't have to check them later.

Another thing we can test automatically, we sorta settled on using an
uppercase letter in in t.Log and t.Fatal calls.

Let's just check for this.

This reverts commit 6416925a.

Count and export number of panics we see.

Fixes #1294

* make pb

* Makefile for pb

Move the Makefile into the pb directory to remove some clutter from the
main Makefile.

* plugin/forward: expose few methods and attributes to public

* Update comments

* Remove Compress by default

Set Compress = true in Scrub only when the message doesn not fit the
advertized buffer. Doing compression is expensive, so try to avoid it.

Master vs this branch

* and make it compile

* plugin/etcd: small refactor

I think this function can be smaller.

* and make it compile

* plugin/cache: per server metrics

Use per server metrics in the cache plugin as well. This required
some plumbing changes. Also use request.Request more.

* fix cherry-pick

* plugin/dnssec: add per server metrics

final plugin.

Fixes #1696 #1492 #1189

* Move cache cap into handler so we can access the server label

* Remove cache-capacity from it entirely

Add server label to the metrics and update the README.

Fixes #1720

Do ' go vet' after we have fetched the repos

Rework the TestProxyClose - close the proxy in the *same* goroutine
as where we started it. Close channels as long as we don't get dataraces
(this may need another fix).

Move the Dial goroutine out of the connManager - this simplifies things
*and* makes another goroutine go away and removes the need for connErr
channels - can now just be dns.Conn.

* plugin/health: update README

Make more clear in the readme that health is limited to 1 server.

Fixes #1722

* rephrase and remove ~~~ corefile because it will fail

* tweak parse error messaging, add tests

* looser err msg checking
