Automatic merge from submit-queue (batch tested with PRs 49842, 50649) Allow passing image description from e2e node test config Ref: https://github.com/kubernetes/kubernetes/issues/42926 This is the follow up of https://github.com/kubernetes/kubernetes/pull/50479. In https://github.com/kubernetes/kubernetes/pull/50479, we added the tests for cos-m60 with docker 1.12.6. Those tests use the same image name as the existing ones (cos-m60 with docker 1.13.1). So we are not distinguish them on node-perf-dash, which categories the tests by image names. This PR fixes the issue by passing image description to the test.
