However, to be forward compatitable, it is suitable to keep 'auto_parallel_search_mode' available. This PR recovers the 'auto_parallel_search_mode' interface and adds a warning when using this old interface.

This PR also deals with other codestyle things.

2) 'sharding_propagation' moves to 'search_mode';
