following guidelines are proposed for image choice in E2E testing.

  * To run release blocking tests, the latest LTS images are preferred.
    'image' should be used to specify the image.

  * To run presubmit, postsubmit or periodic tests, the latest LTS images are
    preferred. If tests need two images, you can use the latest two LTS images.
    LTS images are stable and usually include latest bug and security fix.
