[youngsofun]

I hereby agree to the terms of the CLA available at: https://databend.rs/dev/policies/cla/

Summary

same options used for:

1. input and output
2. copy, clickhouse Format, streaming load.

todo

• add NestedFormatSettings, used for struct/array
  • used in output formats
  • used in input formats (postpone to next pr if no big error)
• use "" for escape by default in CSV output
• unify option processing and parse and use defaults by format
  • map clickhouse type to (Type + Options) internally
  • let options = fmt.f1(settings);
  • let format_setting = fmt.f2(options)
• use nan instead of NaN
• stateful test test_load_unloaded
  • csv
  • tsv ndjson (next pr, need used NestedFormatSettings in input formats )

Fixes #8491
