Currently, nothing progibts to post dublicate registrations to the context broker. This basically the same a with subscription #137
Hence, we require a strategy that checks for matching subscriptions or registrations before posting them and give at least a warning if it will dublicate an existing one.
Describe the solution you'd like
[ ] 1. #138 is an excellent starting point. Let's go from there
[ ] 2. implement a matching strategy for EntityPattern.
[ ] 3. check other fields of subscriptions and registration if they match
[ ] 4. Implement strategy if existing Subscription/Registration already covers the new one, e.g. raise an error.
[ ] 5. Implement strategy if existing Subscription/Registration partially dublicates the new one, e.g. give a merge option.
