Issue:
import-url/get-url: support smth like --config
To be able to pass remote config options on the fly. Similar to `--remote-config` in `import`.

Need to take care figuring out a proper name for this, because we already have `--config` and `--remote-config` elsewhere. So maybe `--url-config`?


Discussion:
I have the need for this use case!
