title: Restart single process with Foreman
body: <p>I've been using foreman for a while now to scale my various ruby processes in a centralized manner, and it is working perfectly for me . </p>
  
  <p>Anyways I would like to have some feature to restart a process or even to give it more control like to kill a process and start it again, in the current implementation when I kill one process the whole process in the main foreman stop . any workaround or solution here  ?</p>
  
  <p>Thanks in advance </p>
