Subject: [PATCH 2/3] [COOK-668] - rearrange postfix service

* Supported platforms (Debian and RHEL families) have status, reload and restart commands in their init scripts, we can specify those as supported by the service.
* the service should be enabled at boot time on all platforms
* Make sure that the service gets started at the end of the recipe since it wouldn't be started, only restarted, elsewhere.
