       * `[CONDITION_ID]` is assigned by Stackdriver Monitoring when the

       * When calling the
       * [alertPolicies.create][google.monitoring.v3.AlertPolicyService.CreateAlertPolicy]
       * method, do not include the `name` field in the conditions of the
       * requested alerting policy. Stackdriver Monitoring creates the
       * condition identifiers and includes them in the new policy.
       * When calling the
       * [alertPolicies.update][google.monitoring.v3.AlertPolicyService.UpdateAlertPolicy]
       * method to update a policy, including a condition `name` causes the
       * existing condition to be updated. Conditions without names are added to
       * the updated policy. Existing conditions are deleted if they are not
       * updated.
       * Best practice is to preserve `[CONDITION_ID]` if you make only small
       * changes, such as those to condition thresholds, durations, or trigger
       * values.  Otherwise, treat the change as a new condition and let the
       * existing condition be deleted.
