Consolidate worker adapter entry points into a single command with sub-commands #557
Description
As suggested by @rafa-be in PR #504:
Currently, there is a specific entry point for each worker adapter. It would be better to have a common scaler_worker_adapter entry point with sub-commands mapping to the name of the adapter.
Example usage:
scaler_worker_adapter fixed --max-workers 10
This would streamline the CLI interface and reduce the number of separate entry points.
As part of this, we need to investigate how to support sub-commands using configargparse (which the project currently uses) or determine if another approach is necessary to achieve this mapping.
