Implement some sort of a clean or on_stop directive

[kindermax]

It may be useful to declare cleanup command.

Example:

commands:
  run: 
   cmd: |
     docker-compose up some-service -d
     npm run app
   on_stop:
     docker-compose down

I will allow to explicitly declare what to do when a command stopped either by error or Ctrl+c

Maybe it will be more clear, if you've name this property after?

Another option is to allow cmd be a list of strings:

foo:
  cmd: echo Foo

bar:
  cmd:
   - echo B
   - echo A
   - echo R

[vharitonsky]

The difference between list of strings and after is that list of strings must be compiled into one multiline shell command which if i set set -ex on top, must exit if some part exits with nonzero status, and after directive is run always, same as in gitlab ci scripts.

[kindermax]

Yes. I think it must be implemented with separate directive after, just like in gitlab ci sript
