[Examples, Question] Outbound-integration node js dependency concerns

[mdgozza]

When reviewing the examples for the Outbound node js integration I found the use of the npm tunnel dependency a little surprising:

https://github.com/vgs-samples/code-examples/blob/master/content-by-language/node/outbound-integration.js#L6-L13
https://github.com/koichik/node-tunnel
https://www.npmjs.com/package/tunnel

I know it seems like it is a very popular package, but it appears to have not been published to in 3 years and the author is about just as active in the space and the package is versioned at 0.0.6.

Proxying http requests in node does not feel like it should require such a dependency, is there a better way?

By including this dependency in the example docs, is VGS recommending tunnel to be safe?

Sorry for the bother! I will try to write up something similar to the dependency and possibly PR it to these examples.

Thanks for all you do, love the product!
