share_server_id is an admin privileged resource and
the tenant facing /share-replicas APIs are currently
returning it.
Fix this by returning the attribute only if the request is
made with administrator context.
Also add updated_at to better reflect when Manila
last updated the replica.
APIImpact:
Please review contractual changes on API Microversion
2.11. This change does not bump up the microversion
since:
- Server still is on 2.11
- /share-replicas APIs are experimental
