Support passing cli args to kaocha

[ieugen]

I think it's quite important to be able to pass cli apps to kaocha.
Kaocha options can be added to config for more stable options.

Some options I care about:

• fail-fast
• run specific tests
• print test plan
• print configuration
• use specific reporters
• etc

Suggestion: I know some programs work by passing all args after this character sequence -- .
This might work.

Having this feature would make debugging test issues like #7 .

This should already be possible to implement in consumers of p-k by providing a :polylith-kaocha/runner-opts->kaocha-poly-opts hook and any of the :polylith-kaocha.kaocha-wrapper/post-*-config hooks.

What I don't know is how to call poly test with extra args in a way that they will be available in the former.
