Enable intrange linter to enforce modern Go range syntax over
traditional for loops, by converting:
for i := 0; i < n; i++
to:
for i := range n
Adding type conversions where needed for compatibility
with existing uint64 parameters.

Enable copyloopvar linter and remove redundant variable
shadowing in Kubernetes plugin metadata handling. This pattern is
no longer needed in Go 1.22+ where loop variables are automatically
captured correctly in closures.

* 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.

Don't explicitly set `RetryOnError` to `false`. It won't exist in the
next version of the k8s api and it won't make a difference in this code
since the struct would default to that.

In kubernetes' audit logs you'll see:
"userAgent":"coredns/v0.0.0 (linux/amd64) kubernetes/$Format"
This change adds a userAgent to the requests made by CoreDNS against the kubernetes API:
"userAgent":"CoreDNS/v1.11.1 git_commit:ae2bbc29be1aaae0b3ded5d188968a6c97bb3144 (linux/amd64/go1.22)"

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.

* Drop obsolete client-go auth plugins
The OpenStack plugin is no longer available, even in version 0.24.4 of
client-go; see
https://github.com/kubernetes/client-go/blob/v0.24.4/plugin/pkg/client/auth/openstack/openstack_stub.go
It is replaced by the client-keystone-auth credential plugin. The
plugin has been entirely removed in client-go 0.26.0, which breaks the
build when any other dependency pulls in client-go 0.26.0 or later.
The GCP plugin is deprecated in K8s 1.22+ and unavailable in 1.26+
(although it is still stubbed in client-go 0.26.0). Is it replaced by
the gke-gcloud-auth-plugin credential plugin.
