Fix for bug 877525

We now have a verbose flag (-v) for run_tests.sh if you want ot see all that
crap printed to the screen.  The default behavior is just to print "test nam
.. OK".  Also, we took the code from nova to cat run_tests.log if there is a
error so that if we hit an import error we will see it in the console jenkin
output.
