Enable errorlint and preserve wrapped error chains so runtime checks
and tests classify failures correctly. This also makes Route53
surface insert failures instead of silently dropping them.

- Added nolint to plugin/auto/walk.go to avoid a symlink/TOCTOU
warning, as it needs to follow symlink.
- Replaced a few flagged integer conversions with safe equivalents in
cache hashing, reuseport socket setup, and TLS arg handling
- Preallocated response rule slices in plugin/rewrite/name.go
- Replaced WriteString(fmt.Sprintf/Sprintln(...)) with direct
fmt.Fprint* calls
- Removed stale nolint directives from code and tests that are no
longer needed

* kubernetes: add multicluster support
Add multicluster support via Multi-Cluster Services API (MCS-API) via a
new option `multiclusterZones` in the kubernetes plugin.
When some multicluster zones are passed to the kubernetes plugin, it
will start watching the ServiceImport objects and its associated
EndpointSlices.

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.

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.
