OSSM Federation Service importAsLocal failed to import same name service in failover case
When we set up OSSM federation between two clusters meshes, if east-mesh has a service as "ratings.bookinfo-ha.svc.cluster.local", east-mesh cannot import a local service uses the same name as an alias.
The following ImportServiceSet failed to import a service from west-mesh to east-mesh
apiVersion: federation.maistra.io/v1

Build Info:
Two AWS OCP 4.9.29 clusters
OSSM 2.1.2
SMCP 2.1.2
How to reproduce:
1. Install operators on two OCP clusters
2. Follow the following federation install.sh , set up federation and wait servicemeshpeer status change to connection: true
This takes 5-20 minutes based on the cloud provider's lb creation time.
https://github.com/maistra/maistra-test-tool/tree/failover/scripts/federation
3. Run the federation install.sh sample again to export and import bookinfo rating service.
