Add REST API endpoint to list related epics
Related to #351597 (closed).
We need a new REST endpoint (similar to the one used by Issue Links API) to list related epics.
We already have API resources that use the term links
and are reserved for parent-child epic hierarchy, so we need to use different naming matching the other resources for this feature (TBC, see #351597 (comment 837691210)).
Example endpoint
GET /api/:version/groups/:id/epics/:epic_iid/related_epics
