node-typescript-app skaffold and helm config

[enriched]

This currently does not work, but I created a issue on the skaffold repository:

GoogleContainerTools/skaffold#961

This looks promising.

Since a lot of people (including myself) aren't familiar with Helm, would you mind including a very short description and link to https://helm.sh?

I opened a separate pull request(#24) for the yarn cache so we can fasttrack that.

I have also been able to get helm and skaffold to work together. It's not great because the default hem configuration separates out the image name and tag, and skaffold relies on finding the full image-name:tag in the values so that it can identify the tag to associate with the image name. Probably won't be able to get around that till reusing tagPolicy variables is implemented. There is someone having a similar issue here.

This PR looks good. I don't mind the workaround for now.

I think this should be good to go for now
