James Lu b3387f2d41 conf: fix deprecation warnings crashing because log is unavailable
This allows conf methods to access to global logger by via an optional 'logger' argument. However,
the caveat is that the logging facilities are still unavailable on first start, because log can
only be imported *after* the configuration is loaded.
