Fixed #885 Now we can take advantage of new argument `--registry` and env overrides: - `CARGO_REGISTRIES_DEFAULT` if `--registry` is not specified - `CARGO_REGISTRIES_{registry_name}_INDEX` for the registry index url We can also read from `.cargo/config.toml` for: - default registry and registries configurations - additional CA bundle `http.cainfo` Signed-off-by: Jiahao XU <Jiahao_XU@outlook.com>
