[RFE] Create a form for projects with broken API

[ingvagabund]

As I golang maintainer I would like to let others to know that my project's dependencies are broken. I would like to have a form where I can fill in my project, dependency with changed API and other related information. As a reaction I would expect an analysis that will tell me what I can do next. If I should ask for an exception, if I should patch my project or broken dependency.

This way packagers can inform each other. Output of all such filled forms would be a list of projects with broken dependencies. It would be another point where upstream maintainers can see what is broken, which deprecated functionality is used, etc.

Required fields for each broken dependency will be its upstream commit. The server will then run apidiff on it and tells what is changed.
