Support adding/setting correlation-id on existing v1 notifications

[olebhansen]

Description

Add support for Correlation-id/"assosiasjons-id", so orders and messages can be linked to Dialogporten and/or other systems. The actual linking is out-of-scope, as the client/other system will have to do the integration.

The use is so e.g. one can query the Notification-API with a dialouge-id as key, and get all notification for that diaouge/dialouge-element (depending on how the correlation is associated).

One use-case is that a user in "arbeidsflate" can drill down in a dialouge, and see if/how a notification was sent for a particular dialouge/transmission.

Tasks

Acceptance criteria:

It is possible to associate notifications with a Dialogporten-dialouge/item, so that this Dialogporten-ID can be used as key for querying the notification API (for current features - there are future changes for a log to improve getting information on the sequence of events, who was notified etc. see #551 ). It is out of scope to improve on the current data-structures beyond #640 to query for individual notifications by id.

Things to discuss

• Future issues if notification is to push events (e.g. to populate Dialogporten with the presence of notifications)... do we need strongly typed keys? Defer this to another structure/problem NOT to be extended from this feature. Introduce a strongly typed validation.
• Other wanted/un-wanted uses, e.g. if implementing as an un-typed list of key-values (that cold cover known feature-requests for tagging a notification as 1st, 2nd, etc.)
• Performance considerations and ability to have efficient indexing/searches
