Merge #11023: [tests] Add option to attach a python debugger if functional test fails

cc5d38f4b Add option to attach a python debugger if test fails (John Newbery)

Pull request description:

  Adds a simple option to the test_framework to attach pdb if the test fails.

  Helpful for catching and debugging intermittent failures: Run the test in a loop with this option. The first failure will cause execution to pause and nodes will be left running for interactive debugging.
