[issue26533] logging.config does not allow disable_existing_loggers=True

[Grazfather x]

New submission from Grazfather x:

logging.config.FileConfig has a kwarg 'disable_existing_loggers' that defaults to False, but when true will allow you to load a config and not disable all other existing loggers.

logging.config.listen uses FileConfig, but has no option to provide this keyword to it, which is a problem when a logger hierarchy is build using logger.getLogger(__name__) (which is recommended in the documentation).

Proposal: Add kwarg 'disable_existing_loggers' to logging.config.listen which is passed to fileConfig.
