Virtuoso - Build bash script for Nodejs agent installation

[carlo-808]

Build out a bash script to facilitate nodejs agent installation on application running on a linux VM.
The goal is to stop a running node application, set up a base level configuration file, install new relic and run the app with the agent using node -r.
This script will eventually be used in a virtuoso recipe.

Note:
We may need to prompt for App Name (PHP team may have some solutions in the works for this)
License key will be available via recipe context

Java recipe for reference
