This PR switches from actions/setup-go@v2-beta to actions/setup-go@v2 to fix the
GitHub Actions `set-env` failure. Without this PR the following error shown up
(see https://github.com/coredns/coredns/runs/1423802307):
```
Error: Unable to process command '::set-env name=GOROOT::/opt/hostedtoolcache/go/1.15.5/x64' successfully.

Error: The `set-env` command is disabled.

Doing a reload every 10ms and sleeping 10ms makes this too racy,
increase all those sleeps to 5ms. A better method would be to get
notified of the reload/change, this would require some polling to get
the RR we expect, with a much longer timeout to stop the test
eventually.

Add github testing workflow, simplify the Makefile because that was
complex because of Travis. Remove the fuzzing, needs to be re-added when
that works properly with go modules (it has been disabled for quite some
time). Multiple builds and files have been added so these tests can all
run in parallel. Our testing now tests a couple of minutes, the codeql
is by far the more expensive.
Move metric's naming test to test/presubmit_test.go
Add longer sleep in the TestAutoAXFR.
Bye bye travis!
Closes: #4266

* plugin/dnstap: remove config struct
this struct is an uneeded intermidiate to get a dnstap it can be
removed. Remove the dnstapio subpkg: it's also not needed. Make *many*
functions and structs private now that we can.

* plugin/dnstap: remove encoder*.go
Those files reimplemented parts of the dnstap spec, we can just use the
dnstap functions for that. This leaves all the queuing that is enabled
and drops messages if the dnstap reader can't keep up. In the new code
flush() would never return an error (at least I couldn't make it do so),
so the reconnect functionally is moved to kick off when we get write
errors.
Some smaller cosmetic changes as well, `d.socket` is now `proto`, which
makes the dial() function smaller.
Total testing time is now <1s (which was the impetus to look into this
plugin *again*).
See #4238
The buffered channel needs to be sized correctly, as we may need to do
some queing if the dnstap reader can't keep up.

* Speed up testing

time from 18s to 0.10s
* reduce time for zone reload
* TestServeDNSConcurrent remove entirely. This took a whopping 58s for

Making values smaller revealed race conditions in the tests. Remove
entirely.
* Move many interval values to variables so we can reset them to short
values for the tests.
* test_large_axfr: make the zone smaller. The number used 64K has no
rational, make it 64/10 to speed up.
* TestProxyThreeWay: use client with shorter timeout
A few random tidbits in other tests.
Total time saved: 177s (almost 3m) - which makes it worthwhile again to
run the test locally:

This brings the total on 20s, and another 10s can be saved by fixing
