We need at least a tiny little shim here to join test file discovery with test invocation. This logic could conceivably be hosted somewhere in python/, but I felt it was strictly the least-rude thing to keep the test logic here in iotests/, even if this small function isn't itself an iotest. Note that we don't actually even need the executable bit here, we'll be relying on the ability to run this module as a script using Python CLI arguments. No chance it gets misunderstood as an actual iotest that way. (It's named, not in tests/, doesn't have the execute bit, and doesn't have an execution shebang.)
