Sharing a Stream Scoped Entity fails with error

[ryan-carroll-graylog]

Ateempting to share a Stream Scoped Entity results in an errror: java.lang.IllegalArgumentException: type <stream_title> does not exist

When sharing an entity there is are checks for any dependent entities in order to warn users that they may need to share the dependencies as well. E.x. if an Event Definition scoped to a Stream is shared, the Stream should be shared as well.

The dependency checking logic is shared with Content Packs, which was updated to support Stream title references in Content Packs. Some updates need to made to the Entity Sharing code to handle these changes.

Workaround

1. Remove any Streams from entity that needs to be shared
2. Share the entity (and dependent Stream)
3. Add Stream back to entity

Expected Behavior

Users are able to share Steam Scoped entities.

Current Behavior

Sharing a Steam Scoped entity results in the error:

Possible Solution

Add the new stream_title type to the GRNRegistry.

Steps to Reproduce (for bugs)

1. Create a Stream Scoped Event Definition
2. Click Share for the Event Definition
3. See error

Noticed this issue after updating to 5.2.3 today.

[coffee-squirrel]

We noticed this under 5.2.3, as well. 5.2.2 appears to be fine.

It seems omitting Streams on the event definitions allows us to proceed with sharing, so we'll just do that as a workaround until the fix lands.
