This should be two different pull request/issues. The one for core should on exposing application properties (name,version,description) to the triggers. The second one should be a pull request to add a swagger activity to contrib or possibly its own repository depending on the amount of dependencies it brings in. We want to limit contrib third-party dependencies to some extent.

Removed swagger activity from core and will move it to contrib as a seperate request.
Current core branch would be for application properties (name,version,description) to the triggers.
