weiminyu 4e71421c81 Support datastore restore in Nomulus tool
Two commands are being added:
- ImportDatastoreCommand starts an async import operation.
  User may choose to wait until import completes or quit
  immediately.
- GetOperationStatusCommand checks the status of an operation.
  It may be used to check the status of an operation started by
  ImportDatastoreCommand.

Both commands communicate with Datastore admin api directly, without
going through the Registry server.
