Add the DNS message response flags as {rflags} to the default logging
Also complete the replacer testing that is was commented out.
And (unrelated) Switch erratic and whoami to ease testing.

Note: {flags} could and should be added as well - but we can leave that
as a beginners bug.

* kubernetes/reverse: remove deadcode
* deadcode in errors and kubernetes removed
* unnecessary conversion
* constants
* proxy: time.Since()
* simplications
* static check
* Disable test/external_test

randomize the times when doing transfers and checks.

Fixes #840

dedent code, use shorter names.
use strings.EqualFold instead ToLower to avoid create garbage.

Use the same OnStartup setup as in the file middleware. We need to copy
the variable from range, otherwise it gets overwriten in the next loop
because of the async goroutine call.

Hard to test, we have secondary_test.go which we could extend with
multiple zones for instance. For now this fix does not have an test case
with it...

Do a go generate to generate all middleware we want/need before
releasing a new CoreDNS version.

Clean up some golint related issues.

Did a `misspell . | grep -v ^vendor` and fixed
several typos.

Define two consts Pod and Svc, makes it stand out a little more
when used in switches in case.

We have opted for a new type, but then you need to convert them
all the time with string(Foo).

* Treat absence of port/service in SRV as wildcard

Normally, a SRV-request should have the form
_<service>._<port>.<name>.<zone>. The k8s peer-finder which is used for
bootstrapping by some applications will however query for SRV at
<name>.<zone>.

To compensate for this behaviour, treat the absence of _<service> and
_<port> as wildcards.

* Modified tests with new SRV behaviour

Added a testcase for a SRV request without port & service
Removed now valid query from invalidSRVQueries

* Forgot to run gofmt on test/kubernetes_test.go

Drop the interfaceAddr interfaces and just use a function. Cleanup
all fallout from that. Remove the use of global variables and cleanup
the tests a bit.

* Added Pod testing

* Cleanup

* fixed formatting

* mw/kubernete: small cleanup

Small cleanup, avoid pointer to []msg.Services and just returns the
msg.Service.

* Actually compile

* testss

SOA would blindly add "." + zone, which when using the root
zone would create a unparseable packet with "name.."

Pull down example middleware and compile it in (this should compile)
then check if dns.example is included in the list of plugins
(middlewares)

Cleanup various READMEs to use the same naming scheme for certs, keys,
and cacerts.

Fixes #762
