Allow findBy on map relationships

[benkuly]

I want to query relationship nodes when they are defined as map.

Given NodeA - RelationsshipProperties -> NodeB:

@Node("NodeA") 
public class NodeA {
        @Id  
        private final String title;

        @Relationship(type = "RELATED_TO", direction = OUTGOING) 
        private Map<NodeB, RelationshipProperties> related = new HashMap<>();
// ...
}

@Node("NodeB") 
public class NodeB {
        @Id  
        private final String title;

        @Relationship(type = "RELATED_TO", direction = INCOMING) 
        private Map<NodeA, RelationshipProperties> related = new HashMap<>();
// ...
}

A Repository Interface-Method Flux<NodeA> findByRelatedTitle(String title); does currently try to access not present title on RelationsshipProperties instead of NodeBs title.

We're discussing atm how we could enhance our @RelationshipProperties-model to make this possible.
