Remove nova v2 client in ListSnapshotImagesTest

ListSnapshotImagesTest should only use nova v3 client for creating
snapshot as the similar test which uses nova v2 client already exist
in nova v2 images api tests(compute/images/test_list_image_filters.py).
This patch removes nova v2 client from ListSnapshotImagesTest.
