Add a class-level comment.

I think the coding style in Blink was more like preferring "self-explanatory"
code than comments.
Neither one of InstallationServiceImpl and AppBannerController have class-level
comments.
Looks like the new coding style does require class-level comment. Thanks for
pointing that out.
Done.
