Add logging

[enyst]

This is WIP rebased on top of the switch to poetry branch. Sorry it's harder to see diff this way; that will be fixed.

@dorbanianas introduced logging on the testing component, this PR brings it in the opendevin module.

Introduce logging, and start replacing print() with logs.

• general logger ./logs/opendevin.log
• also log in console
• special logger for LLM: keeps separate LLM debug logs like we currently have, one file per prompt and one per response, in ./logs/llm
• (Note to self) log json_repair when it did something.
