NodeJS example needs a description in the README

There was some confusion about what this was an example of. We should have a description of it's purpose in the README.md.

Maybe something similar to what we see in the C++ example:
https://github.com/GoogleCloudPlatform/agones/tree/master/examples/cpp-simple

So this is tangental to the issue , but a good place for it, some questions:

1. Are you sure you want to expose the client field externally ? Seems like an implementation detail of the client, not something that should be publically accessible (best would be to solve via scope, but _ is fine too)

And

2. How do you close the connection? Can you provide a top level close or something equivalent ? I'd rather not touch the internal client . I don't feel I should need to touch that to use the client.

Thanks !

Apologies - not sure this is the right place. Once the description has been added to the example, this ticket will be closed, and your questions will be lost for all eternity 😃

If there are improvement to the Node SDK itself, please file individual tickets for each issue 👍, then they can be individually tracked and improved on (looks like this is two tickets - or maybe 2 PRs?)

This example was really useful to create my SDK harness test on Node JS.
Also note that license is missing also:
