don't think funcargs are of primary interest for this but rather other plugins
(like codecheckers) who want to useit to store information. It would also help
to implement persistence across test sessions and features like
"run last failing tests" without having to use "--looponfailing"
from the 'python-xdist' plugin.

this should work on any python and operating system.
The main issue issues i see are
- how to determine the caching-data directory
- how to provide a minimal interface to access and manipulate it.
