Adding Helm Chart for lws

[wqlparallel]

What would you like to be added:
Helm chart is now a normal artifact, widely used in CI/CD systems or displayed in application market, it seems charming if we can support this besides kustomize. I am interested in contributing a Helm chart.

Why is this needed:

• A standard artifact to end-users.

Completion requirements:

This enhancement requires the following artifacts:

• Design doc
• API change
• Docs update

The artifacts should be linked in subsequent comments.
