Support opening default browser from the remote SSH session

Refer to the implementation of aws sso login command.

I think in the meantime it would be a good idea to print on the console the URL that the client is trying to browse to. That would allow me to open my local browser on it and at the end of the process to change the callback URL to point back to the client if I forward the correct port.

@yuezk I just found out it is rather easy to do. You just have to look for a BROWSER environment variable. If there is one, you just run the command $BROWSER $url. And that’s it! And like aws sso, providing a proper URL to open on stdout for cases it is not available would be great!
