Durabletask logger is not respecting root_logger #102

The durabletask package creates its own logger using logging.Logger() directly (not logging.getLogger()), which means it creates an independent logger that doesn't respect the root logger configuration.

def get_logger(
        name_suffix: str,
        log_handler: Optional[logging.Handler] = None,
        log_formatter: Optional[logging.Formatter] = None) -> logging.Logger:
    logger = logging.Logger(f"durabletask-{name_suffix}")

Ideally, the package should be using logging.getLogger() since that enables all customers/clients to easily disable or modify the verbosity of the durabletask-* packages as they need.

 # Explicitly suppress third-party package logs
logging.getLogger("durabletask-worker").setLevel(logging.WARNING)
