Undeploy/kill action

It would be great if centurion supported an undeploy or stop/remove action. Specifically for when you need to retire an app/container or relocate it to a new host. And it could take an optional --host or --hosts option to filter which host you are targeting.

One use-case would be I might deploy a POC app to one shared docker host to test things out in a staging environment, but not want it to be long-lived. You'd have to run the docker stop / remove commands on the host instead of using centurion to remove / retire it.

You should be able to do deploy:stop as your action. It won't delete the image, but it should stop it. The HOSTFILTER equivalent is something that I don't have a quick answer for.

Yea deploy:remove would be a nice task to add IMO. And undeploy could be a deploy:stop followed by a deploy:remove. If I get some free time I'll try and take a stab at it.

There is deploy:cleanup which does this. Currently you'd need two invocations, one to deploy:stop and one to deploy:cleanup. Two options I can think of are:

  1. Allow more than one task on the CLI
  2. Write a wrapper that does this behavior explicitly
