Add visual review toolbar script to public directory
What does this MR do?
This MR adds a script to the public directory of the Rails app. That's pretty weird, right? It's part of gitlab-ee#10761, and it is the script users will include on their review apps in order to inject the toolbar that allows them to post comments directly from their review apps.
That means that it is entirely vanilla Javascript, contained entirely within one file, to fit within the constraints of the project. Someday, if the toolbar gets much larger this may change, but for the MVC, we are doing the stripped down version.
This MR covers the un-styled toolbar and will be followed by MRs adding the script to the MR widget for easy copying and another styling the toolbar in accordance with the documents posted at gitlab-ee#10761.
To see it in action, you can generate yourself a personal token and then can go to the tester app. The review app posts to sarahghp/review-app-tester#1 (closed).
