This reverts commit e75b996e60d912442cf3b2eebb768363f3999c15.
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.
