Context:
Whenever event sources are changed or the model xml is edited it might mean that existing event mappings become invalid. E.g. because a flowNode got removed from the model or if a mapped event is not available anymore as the underlying event source was removed/edited.

In these cases we need an endpoint to be called with the current mappings, the xml and the current event sources which returns a cleaned up mapping.

AT:

• there is a cleanup service endpoint on the eventBasedProcess API
• the endpoint requires an xml, a mapping state as well as a collection of event sources as input and outputs a "cleaned up" mapping where invalid flowNodes as well as events not available among the passed data sources are removed
• authentication checks for the data sources are applied
