Refer log_level parameter in console log handler

Previously while log_level parameter is referred for file handler and
rsyslog handler, it was not used for console handler.
This patch makes sure that the log_level parameter is also effective
for console logger, so that the parameter results in the same behavior
for all log handlers.
