The mondo test tarball containing binaries for all platforms is
DEPRECATED as of Kubernetes 1.14.

Users of this tarball should migrate to using the platform-specific
tarballs in combination with the "portable" tarball which contains
scripts, test images, and other manifests.

For more details, please see KEP
sig-testing/20190118-breaking-apart-the-kubernetes-test-tarball.
