    Fix auth prompt brokenness

    We start by fixing this in the already-present OSC_Config class so OSC
    can move forward. This change needs to get ported down into
    os-client-config in the near future, maybe even soon enough to make the
    client library freeze this week.

    * Add the pw-func argument to the OSC_Config (or OpenStackConfig) __init__()
    * When looping through the auth options from the KSA plugin look for any
      that have a prompt defined and do not have a value already, so ask for one.
