Allow users to add "related resources" to all resources in EventCatalog

[boyney123]

Use Case

I have some users that want to relate resources together, not in a group (domain point of view), but this event (resource) related to this other event, or service etc.

It's just a way that users can group things up visually and let there own catalog users know what resources are related to each other.

Kind of like when you read a doc page and it says "You may also like...".

This would introduce a new field called **relatedResources**
