refactor: clients/* and config.rs (#193)

- add register_clients macro to make it easier to add a new client
- no create_client_config, just add const PROMPTS
- move ModelInfo from clients/ to config/
- model's max_tokens are optional
- improve code quanity on config/mod.rs
- add/use macro config_get_fn
