Finish transitioning to named loggers in Djblets.
Review Request #12679 — Created Oct. 11, 2022 and submitted — Latest diff uploaded
In order to have better context for log messages, we've been moving
things over to use named loggers instead of just relying on the methods
in theloggingmodule. This change finishes up that transition for the
Djblets codebase.
Ran unit tests.
