Reference copy refresh events

[cmgrote]

Need to understand what methods need to be implemented and their intended behaviour.

@mandy-chessell per discussion on call today, if you can help clarify the expected behaviour I should be implementing primarily to be able to respond to any refresh requests (where IGC is the home repository) that'd be great. For now, I can only see these methods in the base MetadataCollection that make any reference to "refresh":

• refreshEntityReferenceCopy
• refreshRelationshipReferenceCopy

... but from today's call my understanding is that these are the methods that cause a request event to be sent for a refresh -- not the methods that respond to such a request. (I'm wondering if the response to such a request may already be handled by the enterprise connector or broader cohort picking up such a request, determining the home repository ID involved, and then simply calling one of the other base methods like getEntityDetail or getRelationship to get the details and then the enterprise connector / cohort bundling the response to that invocation into an event (?) ... rather than a specific method only for responding to such requests in the MetadataCollection...)

Will update, if needed, based on documented interactions from odpi/egeria/issues/2470
