`skaffold verify` can hang indefinitely in deploying for certain errors (ex: deploying into target namspace that doesn't exist)

Issue tracks a bug where if `skaffold verify` is attempting to create a K8s job in a namespace that the user has specified but does not exist, the command will hang indefinitely (vs error stating the ns doesn't exist or possibly creating the ns)

EDIT:  Seems this can also occur when passing in `--rpc-port=0` & `--event-log-file=/dir/not/exist/foo.json`
