Add tests for export location changes in APIv 2.47

- Share export locations API from version 2.47
  will not supply export locations of non-active
  secondary replicas.
- New APIs GET
  /share-replicas/{share_replica_id}/export-locations and
  /share-replicas/{share_replica_id}/export-locations/{export_id}
  provide replica export locations at tenant level by virtue
  of default policy and provide necessary information
  for tenant consumption.
