   * the old subscription or its topic unless the same topic is specified.
   *
   * <p>Sample code:
   *
   * <pre><code>
   * try (SubscriptionAdminClient subscriptionAdminClient = SubscriptionAdminClient.create()) {
   *   SubscriptionName subscription = SubscriptionName.create("[PROJECT]", "[SUBSCRIPTION]");
   *   subscriptionAdminClient.deleteSubscription(subscription);
   * }
   * </code></pre>
   *
   * @param subscription The subscription to delete. Format is
   *     `projects/{project}/subscriptions/{sub}`.
   * @throws com.google.api.gax.grpc.ApiException if the remote call fails
