Previewing dashboard changes using Docker

Dashboard is an Ember app with a lot of dependencies run through NPM and Bower. As such we felt it best to containerise Dashboard to reduce its impact on each engineer's host machine.

To run a live ember server in a container which will rebuild dashboard as you make changes, you will need to be in the dashboard directory in the UX repo. Run docker-compose run --service-ports server. Once that command has successfully run you should have the dashboard available on localhost:4200.
