We support defining DEBUG or VERBOSE_DEBUG to increase the log level per file, but we lack a way to decrease the log level.
The latter could be useful when shotgun debugging with all debug logging enabled, as otherwise some debug output may drown out everything else. To support this, allow LOGLEVEL to be defined per file. We don't expect that any files committed to tree would do this, but it may turn out to be useful during debugging.
