This feature will be particularly useful in situations where users will want to notify various services like the speedcurve or the newrelic after succesful deployment to environments. This feaature can be designed in such a way that it can run a set of task after a successful run of the deployment environment OR after the successful run of all the environments in a deployment projects. For the second aspect, it means we should have a mechanism to trigger the deployment of the whole project rather than just the environment.

At the moment, because of the avialability of this feature, we are able to workaround this issue by piping all the environments to trigger each other with the last environment having a task to do the notification. The downside is that the environments can not be run in parallel and a build failure on one environment will affect the whole deployment
