Ticket 47929 - Admin Server - disable SSLv3 by default
    
    Bug Description:  SSLv3 is no longer safe to use.
    
    Fix Description:  Set the NSS protocol to TLSv1.1 by default, and also
                      properly set the SSL min/max version range(which can
                      also be customized in adm.conf).  Also made sure the
                      new range is properly set and initialized.
