In #440, microsoft/vscode#60773 was mentioned, but that bug has been closed and the issue still persists.

Doesn't work when using vscode with proxy command line flag (i.e. --proxy-server="socks5://...) either.

I encounter the same problem - and indeed everybody working with a the Google Cloud will, too: It is recommended to connect to virtual machines on the Google Cloud via a bastion server [LINK]. The connection needs to be created running the "gcloud" command line utility and this currently cannot be configured in vscode-sftp. Especially, the implemented "connection hopping" functionality cannot handle this setup.

On the command line this can easily be achieved by setting a proxy command in .ssh/config and Microsofts own ssh-connection plugin [LINK] can easily handle this setup.

@development team: Could you please verify, if the same functionality can be implemented in vscode-sftp as well?
