refactor: move rpc handler on_query_configuration_by_index from meta_service to server_state

[levy5307]

In previous implementation, all rpc_handlers in meta server is registered in meta_service. And then the rpc request is forwarded to server_state、bulk_load_service and so on, to handle this request. In this pull request, the rpc handler on_query_configuration_by_index is put to server_state, no need to forward by meta_service
