[qmtest] How do you add prerequisites test from the command line?

[Mohamed Barwani]

To work around this temporarily I had to do the following.. 
Until some comes up with a better solution for parsing TupleFields contained in SetFields.

Apply this patch...

Then I can add prereq tests from the command line like so;
$ qmtest create --id=test_b -a resources="['res_a', 'res_b']" -a prerequisites="['[\'test_a\', \'PASS\']']" -a program=ls test command.ExecTest
