A django-debug-toolbar inspired middleware that allows one to configure tracing at runtime without restarts.

DRF should be a main usecase thus the 'html output appending' technique from DDT can't really be used.

Perhaps a special url /__hunter__/ url where you get a text input for the config and an output pane where any traces will appear.

Prerequisite: https://github.com/ionelmc/python-hunter/issues/54 (enough if html rendering is implemented).

Other considerations:

should work with any server setup (devserver, uwsgi etc - websockets/async not acceptable), possible solutions
- ui makes request to view every sec
- view reads from pipe or something
- tracer writes to pipe - however it should not block too much (perhaps some kind of pipe but a buffer that can discard stuff when it overflows - consider stuff from https://github.com/ionelmc/python-hunter/issues/27)
the UI should have some line limit on output to avoid killing your browser

I like the idea very much. How to find a talented and motivated young developer who wants to do this?
