    authenticate Geni users to CloudLab (who do not have Emulab accounts).
    CloudLab users must have an account to do anything (unlike APT which allows
    guest users). But instead of requiring them to go through the Emulab
    account creation (high bar), let then use their Geni credentials to prove
    who they are. We then build a local account for that new user, and save off
    the speaksfor credential so that we can act on their behalf when talking to
    the backend clusters (and their MA to get their ssh keys).
    These users do not have a local account password, so they cannot log into
    the web interface using the Emulab login page, nor do they have a shell on
    Once authenticated, we put the appropriate cookies into the browser via
    javascript, so they can use the Cloud (okay, APT) web interface (they
    appear logged in).
    I make use of the nonlocal_id field of the users table, which was not being
    used for anything else. Officially, these are "nonlocal" users in the code
    When a nonlocal user instantiates a profile, we use their speaksfor
    credential to ask their home MA for their ssh keys, which we then store in
    the DB, and then provide to the aggregate via the CreateSliver call.
    Note that no provision has been made for users who edit their profile and
    add keys; I am not currently expecting these users to stumble into the web
    interface (yet).
