    NetTestResultSerializer: add method print_summary
    
    This commit adds the method print_summary to the class
    NetTestResultSerializer. The instances of this class contain recipe
    results in DOM form. This was previously used to write results in XML
    form to a file.
    
    The test results can however be also used to provide a nice summary to
    be printed at the end of lnst-ctl execution. This can now be done by
    using the new method.
