Clearly they are required and expected to be set by the ./check script (as evidenced by execute_setup_common(), which checks for test_dir and qemu_default_machine to be set, and aborts if they are not). Using .get() this way has the disadvantage of returning an Optional[str] type, which mypy will complain about when tests just assume these values to be str. Use [] instead, which raises a KeyError for environment variables that are not set. When this exception is raised, catch it and move the abort code from execute_setup_common() there. Drop the 'assert iotests.sock_dir is not None' from iotest 300, because that sort of thing is precisely what this patch wants to prevent.
