The configuration error is that 'ssh_key' (used to populate the 'auth' parameter) is missing, but the error message makes it nearly impossible to diagnose. Node manager should provide better error reporting in this case.

The problem was detected, under [cloud_create] was needed a:
ssh_key: /etc/arvados-node-manager/sshkey.pub
and the file /etc/arvados-node-manager/sshkey.pub should contain a throwaway key. If it's invalid another traceback is triggered:

should also say something that gives a clue to look at /etc/arvados-node-manager/sshkey.pub (or whatever the ssh_key file is)
