operator: Upgrade k8s.io, sigs.k8s.io and openshift deps

[periklis]

What this PR does / why we need it:
Upgrade all required dependencies to enable vendoring openshift/api from release-4.15:

• sigs.k8s.io: v0.15.3 to v0.16.3
• k8s.io: v1.27.7 to v1.28.6
• openshift/api: release-4.14 to release-4.15
• openshift/library-go: release-4.14 to release-4.15

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:

• The replace directive github.com/sercand/kuberesolver is a quick solution to make builds with newer google.golang.org/grpc work again. The module is in the operator's dependency tree because of the direct dependency to Loki.
• The k8.io/utils bump requires replacing the deprecated pointer pkg with it's generic counterpart ptr.To.
• The sigs.k8s.io/controller-runtime bump requires to move from our custom profiler registration to the one provided by the module.

In tests we specify the type of the pointer (Replicas: ptr.To[int32](2)) whereas in code we do not (Replicas: ptr.To(opts.Stack.Template.Ingester.Replicas)), is there any reason?

Why do we maintain a different go.mod for this package? And why do we maintain both with different versions?

[periklis]

We export the APIs for other projects to use like prometheus-operator. Currently known user is https://github.com/rhobs/obsctl-reloader/

Constant integers in Golang resolve to int and not int32 probably cause of their untyped nature.
