Log extra fields not propagating

[vitorguidi]

Extra log fields are not showing up in gcp, ie, docker_image

This issue is meant to map out all missing fields and make sure they show up

I think this is likely due to #3422. These structured logs are only well supported if we use google-cloud-logging. We should hopefully be unblocked there now that the Python upgrade is complete?

Yes, we are unblocked. We run logging 3.6 now (ref)
I suggested this on the monitoring project

Awesome, let's see if we can revive #3422 then
