Revert "move to static LOG"

This reverts commit e75b996e60.

Change is being reverted because we can't actually use a static LOG
object if we expect setup_logging to do the right thing at runtime.
Python logging will load logging objects at import time using the static
LOG object before setup_logging can run otherwise.
