Write CI walkthru

[nicolehaugen]

Write the portion of the walk thru that shows how to setup CI using Jenkins for the microservice version of the app. This includes flushing out the necessary steps.

The CI tasks are something to the effect of:
1.) Configure Git build trigger upon check-in
2.) Ensure node, npm, git and other necessary packages are installed
3.) Run production build tasks (such as minify)
4.) Run unit tests against distribution folder
5.) Deploy production app

Also highlight azure container registry where we're using docker containers.
