Notifications Abonnement Object Filter

[paul-ritense]

Why

Notifications are only sent from notifications API service to GZAC for object types that GZAC is interested in.

• Problem Statement: Without an object filter notifications will be distributed to all 'abonnementen'. This causes unnecessary load to GZAC implementations
• Value Proposition: Reducing the load will prevent unstable GZAC implementations.

How

*Add a objecttype filter to the 'objecten' channel.

What

What needs to be done to implement this feature?

• Feature Description: At startup the NotificatiesApiPlugin creates an 'Abonnement' and includes an 'objecten' channel. By adding a filter to this subscription based on registered objects in the Admin ObjectManagement the subscription will filter on 'create object events'
• Requirements: Use Open Notificaties Version 1.7.0 or higher
• Acceptance Criteria: First manually create object filter, then automate creation of the filter. Add unit tests to create filter and test filter in a test implementation
