    Use chance scheduler in EC2 tests

    The default scheduler switched to the filter scheduler, and apparently
    the EC2 tests are meant to use the chance scheduler for testing. Also,
    compute_scheduler_driver is not recognized when these tests are run
    individually.

    Fixes bug 1075293
