I'm working on adding password based authentication.  To keep the API
the same, I'm thinking of checking if the second credential item is an
existing file, if it is, assume one containing a key.  If not, assume
it's a password.

This should make the use simple in the case of keys:

  with Session(('hostname', port),
               ('username', '/path/to/key')) as session:
      session.cmd('cmd')

And passwords:

  with Session(('hostname', port),
               ('username', 'p@ssw0rD')) as session:
      session.cmd('cmd')

It's being tracked here:

I'll try to have it in Avocado's 72.0 release due next week.

Let me know how that sounds, and thanks for the feedback.
