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.

# ARM64 PYCPP
# In Linux Arm64 presubmit/continuous build, we cross-compile the binaries on
# Linux x86 so that we can use RBE. Since tests still need to run on the single
# host Arm64 machine, the build becomes too slow (~30 min) to be a presubmit.
# For testing purposes, we want to see the runtime performance of an

// preserving values that we allocated on their behalf.  For example, they
// might create a Service without specifying the ClusterIP, in which case we
// allocate one.  If they resubmit that same YAML, we want it to succeed.
