This PR updates go.tidy.yml, and use pseudo name
`coredns-auto-go-mod-tidy[bot]`, so that the commit
is not associated with real user. Otherwise
the commit history could be confusing.

This is similar to what `dependabot[bot]` is doing
for commits generated by bots.

An ISSUE_TEMPLATE directory was added, meaning the ISSUE_TEMPLATE.md is
now obsolete. Remove stale.yml because not used. Symlink CONTRIBUTING.md
the other way around to get GitHub recognize it.

This takes over #3476 because that is a good change but lacks the DCO
and the author seems unresponsive.

Reformat the file a bit more while we're at it.

Closes: #3476
Signed-off-by: Miek Gieben <miek@miek.nl>

Don't sign data we are not authoritative for. This adds an AuthWalk
which skips names we should not authoritative for. Adds a few tests to
check this is the case. Generates zones have been compared to
dnssec-signzone.

A number of changes have been made:

* don't add DS records to the apex
* NSEC TTL is the SOA's minttl value (copying bind9)
* Various cleanups
* signer struct was cleaned up: doesn't need ttl, nor expiration or
  inception.
* plugin/sign: remove apex stuff from names()
  This is never used because we will always have other types in the
  apex, because we *ADD* them ourselves, before we sign (DNSKEY, CDS and
  CDNSKEY).

This splits it up some more; meaning less PRs should hit the top-level
which lists of a lot owners. Still want to keep that list for important
project wide changes

* Fix reloading in plugin/pprof.

Reloading the server without changing the listen address results in an
error because Startup is called for newly set up plugins before Shutdown
is called for the old ones.

* create pkg/reuseport

Move the core server listening functions to a new package so plugins can
use them.

Also make *all* servers use the functions here; as only the udp/tcp
listeners where using SO_REUSEPORT (if available). This is the only
actual change in this PR; in it's core it's just a move of 2 files.

This can also be used to cleanup the dance we're doing now for
re-acquiring the sockets in e.g. the metrics plugins and the ready
plugin.
