SparkSubmitOperation had a single implementation (Kubernetes), so --kill/--status with --master yarn failed with "No external SparkSubmitOperations clients found". Add a YARN implementation backed by YarnClient, registered via ServiceLoader. On a secure cluster the request authenticates with the current ticket cache, or logs in from spark.kerberos.principal/keytab when set. (cherry picked from commit 10d75c3dc0aa2b511b9a76f6762921d85ef4bfaf)
