Do not restart docker at each deployment

[Soulou]

At each chef-client or knife solo cook, docker is stopped then restarted event if nothing has changed, no update, no configuration change.

Maybe it would be more interesting to user notifies :restart, "service[docker]" ? To restart it only when needed. (First deployment, Update and Confinguration change)

👍 it hasn't necessarily bitten me yet, but this doesn't feel right to me. I'd expect restarts only when notified as @Soulou recommends or perhaps adding an attribute checking only_if or not_if to service[docker stop].

Definitely see how this is an issue. Will refactor that code now.

Released 0.9.1 (commit: 91cae5b) that should resolve this issue. Should've noticed this in the original pull request. Sorry about that.
