In order to be able to implement the 'notification' functionality in the frontend, the backend should provide a service of all (relevant) events that happened on a playground initiative.
DoD:
[x] service that exposes all (*) events of a playground
[x] (*) limit the events to recent events if the total number of events become too large to handle (detailed specs TBD)
[x] poll for these events so the frontend can be updated automatically
[x] filter the relevant event on the backend and only expose non-sensitive events and non-sensitive attributes
[x] textual translation of the event data into messages is to happen on the frontend
