Shane Smiskol cfc2cda37c separate car logger forwarded to cloudlog (#33170)
* car logger

* try this

* fix double printing!

* clean up

* need to import where we actually use it (card won't be in submodule)

* NullHandler does not forward everything properly, need propagate=False to stop root logger from printing

* card is staying

* set up

* forward
