Give more flexibility to launch the asphalt application

[KenKi0]

I encountered a problem that with my plugins, asphalt start timeouts, but I didn’t find functionality to control this parameter for starting the asphalt application.

I propose to give the ability to specify the path to config.yaml, and if it is specified, then load it. I also propose to rework the get_config function to compile config using the pyyaml ​​tool, instead of doing it manually.

How i see it in code:

def get_config(disable: Tuple[str, ...], config_path: Path | None = None) -> str:
    jupyverse_components = [
        ep.name
        for ep in entry_points(group="jupyverse.components")
        if ep.name not in disable
    ]
    if config_path:
        config = yaml.safe_load(config_path)
    else:
        config = {}
    component = {
        "type": "jupyverse",
        "components": {
            component: {"type": component}
            for component in jupyverse_components
        },
    },
    logging_conf = {'disable_existing_loggers': False,
         'formatters': {'default': {'format': '[%(asctime)s %(levelname)s] '
                                              '%(message)s'}},
         'handlers': {'console': {'class': 'logging.StreamHandler',
                                  'formatter': 'default'}},
         'loggers': {'webnotifier': {'level': 'DEBUG'}},
         'root': {'handlers': ['console'], 'level': 'INFO'},
         'version': 1}
    config["component"] = component
    if not config.get("logging"):
        config["logging"] = logging_conf
    

    config_str = yaml.dump(config)
    return config_str
