Port REST API debug panel from flask

[jettify]

Flask has nice panel for debugging REST API we should port it somehow

That debug panel looks nice. I have been considering porting django-rest-framework's browsable API, but I'm unsure if it's worth the effort given that (1) This panel would provide very similar functionality and (2) I don't use the browsable API that much, even when using DRF--I typically use Postman when I need a GUI client.

Thoughts?

Code for flask-debug-api is short and clean.
aiohttp 0.18+ allows to iterate over registered routes.
And yes, Postman is great tool.
