Override gkeconnect_gateway_v1::GatewayControlClient Retry Policies

This shows how to override the retry policies for gkeconnect_gateway_v1::GatewayControlClient:

  auto options = google::cloud::Options{}
                     .set<google::cloud::gkeconnect_gateway_v1::
                              GatewayControlConnectionIdempotencyPolicyOption>(
                         CustomIdempotencyPolicy().clone())
                     .set<google::cloud::gkeconnect_gateway_v1::
                              GatewayControlRetryPolicyOption>(
                         google::cloud::gkeconnect_gateway_v1::
                             GatewayControlLimitedErrorCountRetryPolicy(3)
                                 .clone())
                     .set<google::cloud::gkeconnect_gateway_v1::
                              GatewayControlBackoffPolicyOption>(
                         google::cloud::ExponentialBackoffPolicy(
                             /*initial_delay=*/std::chrono::milliseconds(200),
                             /*maximum_delay=*/std::chrono::seconds(45),
                             /*scaling=*/2.0)
                             .clone());
  auto connection =
      google::cloud::gkeconnect_gateway_v1::MakeGatewayControlConnectionRest(
          options);

  // c1 and c2 share the same retry policies
  auto c1 =
      google::cloud::gkeconnect_gateway_v1::GatewayControlClient(connection);
  auto c2 =
      google::cloud::gkeconnect_gateway_v1::GatewayControlClient(connection);

  // You can override any of the policies in a new client. This new client
  // will share the policies from c1 (or c2) *except* for the retry policy.
  auto c3 = google::cloud::gkeconnect_gateway_v1::GatewayControlClient(
      connection,
      google::cloud::Options{}
          .set<google::cloud::gkeconnect_gateway_v1::
                   GatewayControlRetryPolicyOption>(
              google::cloud::gkeconnect_gateway_v1::
                  GatewayControlLimitedTimeRetryPolicy(std::chrono::minutes(5))
                      .clone()));

  // You can also override the policies in a single call:
  // c3.SomeRpc(..., google::cloud::Options{}
  //     .set<google::cloud::gkeconnect_gateway_v1::GatewayControlRetryPolicyOption>(
  //       google::cloud::gkeconnect_gateway_v1::GatewayControlLimitedErrorCountRetryPolicy(10).clone()));

Assuming you have created a custom idempotency policy. Such as:

class CustomIdempotencyPolicy : public google::cloud::gkeconnect_gateway_v1::
                                    GatewayControlConnectionIdempotencyPolicy {
 public:
  ~CustomIdempotencyPolicy() override = default;
  std::unique_ptr<google::cloud::gkeconnect_gateway_v1::
                      GatewayControlConnectionIdempotencyPolicy>
  clone() const override {
    return std::make_unique<CustomIdempotencyPolicy>(*this);
  }
  // Override inherited functions to define as needed.
};
