Enable Remote Debugging

[mhoeger]

The underlying platform is implementing a way to remote debug. Currently, this should work on App Service Linux machines with the addition of language worker arguments to enable debugging (article here: https://medium.com/@auchenberg/introducing-remote-debugging-of-node-js-apps-on-azure-app-service-from-vs-code-in-public-preview-9b8d83a6e1f0)

We need to:

1. Make sure that this works and document in this issues
2. Automate any steps that (such as adding a debug argument app setting)

Both steps need to be done for Linux and Windows (separate implementations)
