   ### Description of PR
   If a cluster has 3 nameservices: ns1, ns2,ns3, and  ns1 has observer nodes, and client  comminutes with nameservices via DFSRouter.
   
   If DFS_ROUTER_OBSERVER_READ_DEFAULT_KEY enable,  the client will receive all nameservices in RpcResponseHeaderProto.  And ns2,ns3 statidid is Long.MIN_VALUE,that is not necessary.
   
   We should reduce rpc response size if nameservices don't enable observer nodes.
