Tests located in ${KUBE_ROOT}/test/e2e/common are shared by both Cluster
and Node E2E test jobs. Tests in ${KUBE_ROOT}/test/e2e_node are exclusively
owned by Node E2E. If you want to add a test, most likely than not, you want
to add the test to one of the two directories mentioned above. If you are
unsure, please check with the OWNER of the directory. This directory currently
contains misplaced and legacy tests; they will be cleaned up in the future.
