I'm in charge of Gapic codegen and GAX for NodeJS

• gax: https://github.com/googleapis/gax-nodejs
• code generator: https://github.com/googleapis/toolkit

It was an independent effort, but recently we reached to an agreement that bringing the generated code into a part of gcloud itself.

It's still unclear to me where the generated code will be located and how these files are accessible from users, so this is an issue to discuss about these things.
