Add flag --failed to kunit.py to print only failed tests. This printing is done after running is over.
This patch also adds the method print_test() that will also print your Test object. Before, all printing of tests occurred during parsing. This method could be useful in the future when converting to/from KTAP to this pretty-print output.
