Add helm chart

[honghainguyen777]

Description

Add a Helm chart for deploying the node-readiness-controller.

This chart installs the node-readiness-controller along with the required
Kubernetes resources, including:

• Deployment for the controller
• RBAC resources
• Metrics and webhook services
• ValidatingWebhookConfiguration
• NodeReadinessRule CRD
• Optional NodeReadinessRule resources configurable via values.yaml

The chart follows conventions used by existing charts in https://github.com/kubernetes-sigs
(e.g. descheduler) and supports customization via Helm values.

Hi @honghainguyen777. 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.
