Implement a hook_requirements requirement to report that Retrofit is running

[mglaman]

Feedback from TCDrupal presentation was to add some kind of status report that Retrofit is running on the site.

Is it possible to implement hook_requirements when there isn't a module?

Or are you running on some sort of advanced wizardry level I haven't even contemplated? 🧙‍♂️

I haven't decided. It could be one of the following:

• The module_handler is already decorated so I could check if invokeAll is called with requirements to hook in
• Decorate SystemManager and add the Retrofit status item to the top of the items returned with listRequirements
