Upgrade K8s Dependencies to v0.30.4

[sujeet01]

This PR upgrades our Kubernetes package dependencies from v0.29.4 to v0.30.4 and implements necessary code refactoring to accommodate breaking changes.

Proposed Changes:

• Upgrade K8s Dependencies: Bumped k8s.io/* dependencies from v0.29.4 to v0.30.4 to incorporate the latest features and improvements. Fixes Bump k8s.io/* deps to v0.30 #1113
• Upgrade Controller-Runtime: Bumped sigs.k8s.io/controller-runtime from v0.17.3 to v0.18.5 to ensure compatibility with the upgraded k8s dependencies.
• Refactor for Breaking Changes: Adjusted code to address breaking changes introduced in the new version.
• Update Code Generation Script: Adapted hack/update-codegen.sh script to utilize the kube_codegen.sh script functions, aligning with updated k8s code generation standards.
• Update OpenAPI-Gen Package: The openapi-gen has been removed from k8s.io/code-generator by PR #123529 because it is redundant with the version in k8s.io/kube-openapi.
• Update Makefile: Updated ENVTEST_K8S_VERSION from 1.28.0 to 1.30.3 and performed cleanup by removing obsolete generation tool binaries.
• Run Make Generate: Executed make generate to apply all code generation tasks with the updated setup.
• Update Import Paths: Updated import paths to match the new locations of the generated client code.

Fixes #1094

For me make generate fails on an clean project with:

./hack/update-codegen.sh: line 12: /kube_codegen.sh: No such file or directory

I would suggest to modify the hack script to fetch it from the correct location in the go mod cache.

Thanks for catching this issue. I have addressed this in the latest commit by reordering the steps in the hack script to download dependencies before setting CODE_GEN_DIR. This should resolve the problem, and make generate should now work as expected on a clean project.
