Jouni Malinen de684a2b83 tests: Add run-tests.py --shuffle-test
This optional argument can be used to randomize the order in which the
test cases are run. This can provide more coverage on testing
interactions of common use cases in various different sequences. Such
issues have already been found even with the fixed order of test cases,
but being able to reorder the tests makes this more efficient.
