Ticket 47929 - adminutil - future proof getSSLVersion
    
    Bug Description:  Currently all the SSL versions are hardcoded, so as
                      new versions are released the code will also need to
                      be updated.
    
    FIx Description:  Take a version string and convert it to the SSL version
                      identifier.  Also verify that the max and min versions
                      are within the acceptable ranges, if not adjust them.
