test_minimum_basic_scenario fails with Tempest 27.0.0 due to removed img_dir option

[Pierre Riteau]

After setting up a new verifier which pulled tempest 27.0.0, test_minimum_basic_scenario fails because it relies on the img_dir option which was removed from tempest.

tempest.scenario.test_minimum_basic.TestMinimumBasicScenario.test_minimum_basic_scenario

rally-openstack needs to be updated to use img_file only.

    Stop using removed option [scenario]/img_dir

    The [scenario]/img_dir configuration option was removed from tempest in
    version 27.0.0. This makes test_minimum_basic_scenario fail with:

    FileNotFoundError: [Errno 2] No such file or directory: 'tempest-image'

    Use [scenario]/img_file with a full path to the image instead.

    + skip several tests at CI
