This simple utility function configures default python logging to log on stdout and SYSLOG with default configuration and formatters.
The default level is INFO. If it is called a second time, by default it will disable ALL existing loggers (disable_existing_loggers = True). If called with disable_existing_loggers = False, ALL existing loggers will be enabled. The function also resets the handlers and only cii-console and SYSLOG will be set, i.e. any other handler will be removed. disable_existing_loggers (default True): if specified as False, loggers which exist when this call is made are left enabled. The default is True because this enables old behaviour in a backward-compatible way. This behaviour is to disable any existing non-root loggers unless they or their ancestors are explicitly named in the logging configuration.
