    Kerberos as method name
    
    To date kerberos has been supported by the "external" method
    name.  However, the Client plugin architecture needs to refer to the
    method name , and we do not want to expose to the client the
    difference between kerberos as performed by an external module or
    an eventual kerberos-in-eventlet style implementation.
    
    If the "external" plugin is missing, the old code would throw an
    exception attempting to process "REMOTE_USER" behavior.  If only
    'Kerberos" is specified, this is checked and skipped.
    
    Blueprint: kerberos-authentication
    SecurityImpact:  Minimal, as Kerberos is already used via external,
                     this  just changes the main way it is named.
