Provide a helm chart for installing virtink

[weixiao-huang]

Could we provide a helm chart for installing virtink instead of only using kubectl apply? It it is needed, I can submit a PR to try to add a helm chart

Sure thing! I'd be happy to review it if you send us a Helm chart PR.

See https://github.com/smartxworks/virtink-charts, but that one seems to be a bit behind.
