[Refactor]: config

[themanforfree]

Now all of our configurations are in a single file, utils/src/config.rs，It also contains a lot of parse_xxx, xxx_format, default_xxx methods, It's messy and difficult to manage. We need to organize these configurations into modules, each containing the configuration itself, its parse method, and default values.

In addition, the configuration can only be created through the new method, which is very inflexible, we need to refactor them use builder pattern, and it should be easy to modify existing configurations
