@ttomasz a gentle reminder :) or can we close this PR?

Sorry, was quite busy past few months 😅 I should be able to finish this up in June.

Changed popping kwargs to separate parameter for stuff to pass to underlying library.

[ttomasz]

Sorry for the mess with the commits. Do you want me to revert client_args/connect_args to being kwargs instead of parameter? Or is the current state ok?

Can I ask for this PR to get revived? I too need to pass options to asyncssh.SSHClientConnection.start_sftp_client().

I need to override the default sftp_version due to hitting ronf/asyncssh#587
