Add Pod Annotations and Labels to Helm Chart

[sanderv32]

This PR introduces support for adding custom annotations and labels to Pods created by the Helm chart. This enhancement provides better flexibility and allows for improved integration with external systems and workflows that rely on annotations or labels.

Changes:
• Added support for specifying Pod annotations in the values.yaml file.
• Added support for specifying Pod labels in the values.yaml file.
• Updated the templates/hnc-controller-manager-ha.yaml and templates/hnc-controller-manager.yaml files to include the provided annotations and labels.
• Verified changes to ensure backward compatibility when no annotations or labels are specified.

Why this change is necessary:
This change enhances the Helm chart’s configurability, enabling users to:
• Integrate with monitoring or logging tools that depend on specific annotations.
• Apply workload-specific metadata using labels for easier management and organization.

Hi @sanderv32. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
