Visualize service endpoints contributed through federation

As a mesh administrator, with a mesh ("mesh 1") that is federated with one or more other service meshes ("mesh 2") - which may reside in the same cluster or a different cluster, I want to combine a service in my mesh ("service A") with a service in a different mesh ("s ervice A' ") - such that traffic directed at service A, may be handled by service A' in mesh 2 in the event that service A is not available. This creates an HA / failover relationship between the two services. These two services may have the same or different names.  As a mesh administrator, I want to be able to verify that endpoints contributed by other meshes are available for local services.

Acceptance Criteria:

From mesh 1's perspective:

• I am able to validate that service A is aggregated with service A' in mesh 2 via some "oc" commands as well as Kiali.

From mesh 2's perspective:

• I am able to validate that service A' may receive traffic from service A in mesh 1 (or validate that I have given permissions for this)
