Ticket 32 - Add TLS external bind support for testing
    
    Bug Description:  Previously it was difficult to test TLS external
    binds. We should add this to lib389 before any refactor of the
    certmap code.
    
    Fix Description:  This covers a number of locations. Importantly:
    
    * The ability to configure certmaps programatically via config.
    * The ability to generate and extract user certificates signed
        by the internal CA from lib389
    * The ability to perform an external TLS bind.
