chore: Upgrade dependences and go version

[cychiang]

Background

The vcluster has up-to-date version of some dependencies than vcluster-sdk. I think it's good to keep these two in the same position in terms of the go version and dependencies.

Summary

• Replace deprecated implementations with recommended ways

  • genericclioptions is deprecated and replace by genericiooptions
  • cluster.NewClientFunc has been replaced by client.NewClientFunc
  • PollImmediateInfinite has been deprecated and recommended to use PollUntilContextCancel instead
  • MetricsBindAddress and Namespace has beed removed from manager.Options
  • WithInsecure is deprecated and replace by WithTransportCredentials

• Bump up controller-runtime related libraries to the latest version as following:

k8s.io/api v0.26.1 -> v0.28.2
k8s.io/apiextensions-apiserver v0.26.1 -> v0.28.2
k8s.io/apimachinery v0.26.1 -> v0.28.2
k8s.io/cli-runtime v0.26.1 -> v0.28.2
k8s.io/client-go v0.26.1 -> v0.28.2
k8s.io/klog/v2 v2.90.0 -> v2.100.1
k8s.io/kube-aggregator v0.26.1 -> v0.28.2
k8s.io/kubectl v0.26.1 -> v0.28.2
sigs.k8s.io/controller-runtime v0.14.4 -> v0.16.2

Please help me to refine this PR and becomes ready to merge. 😄

@cychiang I ran into your PR as I depend on vcluster-sdk and tried to upgrade controller-runtime to 1.16+. This PR is missing a few changes to make it compile: https://github.com/cychiang/vcluster-sdk/pull/1
