Add a NativeHistogramBucketFactor parameter to the use of
`NewHistogramVec` in order to enable use of Prometheus Native
Histograms.
This will store automatically computed sparse buckets in CoreDNS.
If a compatible Prometeus requests native histograms this data will
returned instead of the static buckets.
The default factor of 1.05 should provide high quality resolution data.

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.

Cleanup a variety of metric issues.
* Eliminate department of redundancy "count_total" naming.
* Use the plural of the unit when appropriate. (ex, "requests")
* Remove label names from metric names where appropriate. (ex, "rcode")
* Simplify request metrics by consolidating type label in to the base
request counter.
* Re-generate man pages.

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).

Remove all these uses and just make them work on caddy.Controller. Also
don't export parsing functions as their should be private to the plugin.

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.
