Now launcher use ssh when attach to workers, there are some problem:

  1. it needs workers open sshd
  2. controller needs to create a keyPair as secret for every job
  3. it makes controller hard to know whether worker training process is shutdown when scaleIn job

A better way is using kubectl exec to replace ssh.
