SSH with 2FA doesn't work

[andersy005]

I just confirmed that the existing authentication mechanism doesn't work when using 2 factor authentication on Casper

https://github.com/NCAR/jupyter-forward/blob/eb59c2e91b697afe65ac80ca77f6711ece9d9185/jupyter_forward/core.py#L84-L85

Running something along these lines

❯ jupyter-forward start abanih@casper.ucar.edu --notebook-dir /glade/scratch/abanihi 

raises the following exception

paramiko.ssh_exception.BadAuthenticationType: Bad authentication type; allowed types: ['keyboard-interactive']

I found out I was wrong about this. I was inputting the wrong password. I can confirm the authentication works on both casper and cheyenne as well. @halehawk, thank you for your feedback!
