 * Runtime binding for the `ModifyCapacityReservation` operation (IAM action

 *
 * Sets or resets the bound load balancer's minimum LCU capacity reservation
 * at runtime — e.g. a Lambda that pre-provisions capacity ahead of a known
 * traffic spike (product launch, ticket sale) and resets it afterwards, the
 * ELBv2 analogue of Auto Scaling's `SetDesiredCapacity`. Provide the
 * implementation with
 * `Effect.provide(AWS.ELBv2.ModifyCapacityReservationHttp)`.
 * ### Capacity Reservation
 * **Example:** Reserve capacity ahead of a spike
 * ```typescript
 * // init — bind the operation to the load balancer
 * const modifyCapacityReservation =
 *   yield* AWS.ELBv2.ModifyCapacityReservation(loadBalancer);
 *
 * // runtime — reserve 100 LCUs per Availability Zone
 * yield* modifyCapacityReservation({
 *   MinimumLoadBalancerCapacity: { CapacityUnits: 100 },
 * });
 *
 * // later — release the reservation
 * yield* modifyCapacityReservation({ ResetCapacityReservation: true });
 * ```
