Review ewoksserver settings

!117 (comment 349316)

Currently we have this pydantic model for the ewoks server configuration

class EwoksSettings(BaseModel):
    configured: bool = Field(
        default=False, title="Config or resource directory have been defined"
    )
    resource_directory: Path = Field(
        default=Path("."), title="Backend file resource directory"
    )
    ewoks: Optional[Dict] = Field(default=None, title="Ewoks configuration")
    celery: Optional[Dict] = Field(default=None, title="Celery configuration")
    without_events: bool = Field(default=False, title="Enable ewoks events")
    discover_tasks: bool = Field(default=False, title="Discover ewoks tasks on startup")

So ewoks refers to the execution (we should have called it ewoks_execution or something) and afaik only "handlers" is used. Perhaps this need to be a model as well.

The DISCOVER_TIMEOUT and discover_tasks are both ewoks as well, but not execution. So ewoks_discovery for example.

Do you think we could do something like this and deprecate where needed?

ewoks_discovery can also contain discover_tasks.
