While performing security scans there were several
issue raised as G304 (CWE-22): Potential file inclusion via variable.
As some files path are taken from user input, it is possible the
filepath passed by user may have unintended effect if not properly formed.
This fix add Clean to remove the security warning and address some
potential issue.

Make normalize return multiple "hosts" (= reverse zones) when a
non-octet boundary cidr is given.
Added pkg/cidr package that holds the cidr calculation routines; felt
they didn't really fit dnsutil.
This change means the IPNet return parameter isn't needed, the hosts are
all correct. The tests that tests this is also removed: TestSplitHostPortReverse
The fallout was that zoneAddr _also_ doesn't need the IPNet member, that
in turn make it visible that zoneAddr in address.go duplicated a bunch
of stuff from register.go; removed/refactored that too.
Created a plugin.OriginsFromArgsOrServerBlock to help plugins do the
right things, by consuming ZONE arguments; this now expands reverse
zones correctly. This is mostly mechanical.
Remove the reverse test in plugin/kubernetes which is a copy-paste from
a core test (which has since been fixed).
Remove MustNormalize as it has no plugin users.
This change is not backwards compatible to plugins that have a ZONE
argument that they parse in the setup util.
All in-tree plugins have been updated.

* Speed up testing
* make notification run in the background, this recudes the test_readme
time from 18s to 0.10s
* reduce time for zone reload
* TestServeDNSConcurrent remove entirely. This took a whopping 58s for
... ? A few minutes staring didn't reveal wth it is actually testing.
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:

plugins/ -40s
This brings the total on 20s, and another 10s can be saved by fixing
dnstapio. Moving this to 5s would be even better, but 10s is also nice.

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

This PR adds a expiration jitter to spread out zone re-signing even
more. The max is 5 extra days added when creating the signer for a
specific zone.
Also make the duration* constants private to clean up the godoc for this

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).

Caught my eye, we name things directive still, esp when talking about
the prometheus *plugin*. Rename everything that needs to be plugin to
'plugin'. Also make sure Metrics is a H2 section (not H1).

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/sign: a plugin that signs zones
Sign is a plugin that signs zone data (on disk). The README.md details
what exactly happens to should be accurate related to the code.
Signs are signed with a CSK, resigning and first time signing is all
handled by *sign* plugin.
Logging with a test zone looks something like this:
~~~ txt
