Pull Request Overview

This PR fixes a bug in the Kubernetes cluster creation process where network offering validation was incorrectly using the global setting instead of validating the network offering from the provided network. The fix ensures that when a specific network is provided for cluster creation, its network offering is validated rather than relying solely on the global configuration.

• Updates network offering validation logic to check the provided network's offering when available
• Adds proper null checks and error handling for network lookup
• Maintains backward compatibility with global network offering configuration

Tested OK

• Register CKS ISO
• Set global config endpoint.url
• Update cloud.kubernetes.cluster.network.offering setting from DefaultNetworkOfferingforKubernetesService to DefaultNetworkOfferingforKubernetesService2
• Create a CKS cluster without network, fail with error: Kubernetes service has not been configured properly to provision Kubernetes clusters. this is expected
• Create network with offering DefaultNetworkOfferingforKubernetesService
• Create a CKS cluster with the network
  • Without this PR: fail with error: Kubernetes service has not been configured properly to provision Kubernetes clusters. this is expected
  • With this PR: CKS cluster is created successfully
