* Update samples for nodejs + nodejs-google-cloud-functions.
* Fix example generator to use deterministic randomness.
This avoids changing results after each generation, and makes diff reviews easier.
* Update NodeJS samples.
This is the last "randomness" update. From now on the samples should only change if either the generator, the input or parameters change.
* Another approach: extending NodeJS server to support GCF.
This does not add a new language, but adding some client options
to support Google Cloud Functions (GCF).
* Add URLs for how to deploy the generated code.
Adds the client options help message and the README.md file.
