Description

Hi! Just got a feature idea that might be a nice-to-have maybe?: supporting taking .ssh/config for parameters

i.e. just like we do sftp nickname in console, maybe we could connect as fsspec.filesystem('sftp', host='nickname') instead of fsspec.filesystem('sftp', host='XXX.XXX.XXX.XXX', port=XXX, username='XXX', password='XXX'), so we can have less hard coding and won't be saving passwords in plain text.

I raised a question on StackOverflow being unsure before, and now checking out after receiving a comment.

Great thanks for the effort for the great package!

Research direction

Start by tracing how the SFTP filesystem handles host, port, username, and password parameters, then determine where an SSH config nickname could be resolved. Done means fsspec.filesystem('sftp', host='nickname') can use .ssh/config parameters without requiring hard-coded connection details or plain-text passwords.
