Ticket 49474 - Improve GSSAPI testing capability
    
    Bug Description:  GSSAPI is difficult to test correctly. Having
    support for it as a topology in lib389 will mak ethis easier.
    
    Note that these tests require specific dns and hosts settings.
    
    Fix Description:  Improve the ability to integrate accounts with
    principles, bind them with GSSAPI, oru ability to return valid
    uris with krb realms, our saslmap capabilities and create a
    single master gssapi topology.
