feat(config:line): 支持自定义线路参数 (#501)

* Initial plan

* Add line configuration support for DNS providers

Co-authored-by: NewFuture <[email protected]>

* Add line parameter documentation to CLI, ENV, and README

Co-authored-by: NewFuture <[email protected]>

* Implement line parameter in config.py and update v4.0 schema, fix lint issues
