K8s 1.30

[vardhaman22]

Issue:

#45089

Problem

As per the issue k8s minor version 1.30 support needs to be added

Solution

updated all the k8s libraries to kubernetes v1.30.0

other changes done:

1. updated wrangler from v2 to v3

2. replaced k8s.io/gengo/examples/set-gen/sets with "k8s.io/apimachinery/pkg/util/sets" since gengo is updated to gengo/v2 in kubernetes v1.30.0 and sets package is removed from gengo/v2 ref

3. and since gengo args package is also removed in gengo/v2 so removed args.DefaultSourceTree() function uses and added the implementation of that function directly in the code.

similar thing is done in a PR for rancher/norman

4. apiserver types moved from one dir to another
   kubernetes/apiserver@e7eedd1#diff-179ab44de4a16de69e23c8a3fee5a0d6ef22755b90c182744f05ca9e1eca4381
   so updated imports in rancher ref

5. bumped controller-runtime to v0.18.2 and cluster-api to v1.7.2 also updated capi crds and capi webhook yaml files.
   updated capi webhooks with custom changes also which is rancher specific change ref

6. after updating capi crds an error occurred while running rancher

2024/05/17 08:06:42 [ERROR] error syncing 'cluster-member': handler auth-prov-v2-roletemplate: no matches for kind "Machine" in version "cluster.x-k8s.io/v1alpha3", requeuing
    2024/05/17 08:06:42 [ERROR] error syncing 'cluster-admin': handler auth-prov-v2-roletemplate: no matches for kind "Cluster" in version "cluster.x-k8s.io/v1alpha3", requeuing
    2024/05/17 08:06:43 [ERROR] error syncing 'cluster-owner': handler auth-prov-v2-roletemplate: no matches for kind "Cluster" in version "cluster.x-k8s.io/v1alpha3", requeuing

cluster.x-k8s.io/v1alpha3 is deprecated in capi v1.7.2 but it is still in crd. So fixed rancher code to not add deprecated version of a resource from a crd to validate role data. ref

7. updated python tests test_node_fields and test_dns_fields fix needed because of addition of new fields in k8s v1.30 for these objects.

8. updated local cluster k3s version to v1.30.0+k3s1 and also updated rancher chart kube-version annotation.

9. bumped kubernetes libraries to v0.30.1

10. updated golangci lint to v1.58.1 (was the latest version when i started working on this PR...needs to be bumped to v1.59.0 since it is the latest version).

NOTE: for initial verification used forked dependencies, custom KDM, custom charts repositories and did additional changes needed for these for testing.
