Traffic is a plugin that communicates via the xDS protocol to an Envoy
control plane. Using the data from this control plane it hands out IP
addresses. This allows you (via controlling the data in the control
plane) to drain or send more traffic to specific endpoints.
The plugin itself only acts upon this data; it doesn't do anything fancy
by itself.
Code used here is copied from grpc-go and other places, this is clearly
marked in the source files.

1. The HostPortOrFile tests don't have any IPv6 tests. This adds some.
2. The HostPortOrFile breaks if any of the addresses have IPv6 zone
defined. ParseIP does not handle %zone anymore.

* sign: add expiration jitter
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
plugin.

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).

* 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.

When reloading we need to disable debug output when the debug plugin is
removed from the config file. Add a `Clear` function to pkg/log and use
it in the server server.
Add test case in pkg/log, for actuall check I manually checked the
output by sprinkling some debug statements in the startup and checking
with sending SIGUSR1.
Also clear up the comments in pkg/log to remove the text about time
stamping.

Caught my eye, we name things directive still, esp when talking about

'plugin'. Also make sure Metrics is a H2 section (not H1).

For now metric is measure only for headless services. Informer has been slighlty

* Make request.Request smaller
This makes the request struct smaller and removes the pointer to the do
boolean (tri-bool) as size == 0 will indicate if we have cached it.
Family can be a int8 because it only carries 3 values, Size itself is
just a uint16 under the covers.
This is a more comprehensive fix than #3292Closes#3292

Don't perform this code in the init, this allocated 1 megabyte of memory
