// Modifies the status of an Amazon ECS container instance. Once a container
// instance has reached an ACTIVE state, you can change the status of a container
// instance to DRAINING to manually remove an instance from a cluster, for example
// to perform system updates, update the Docker daemon, or scale down the cluster
// size. A container instance can't be changed to DRAINING until it has reached an
// ACTIVE status. If the instance is in any other status, an error will be
// received. When you set a container instance to DRAINING , Amazon ECS prevents
// new tasks from being scheduled for placement on the container instance and
// replacement service tasks are started on other container instances in the
// cluster if the resources are available. Service tasks on the container instance
// that are in the PENDING state are stopped immediately. Service tasks on the
// container instance that are in the RUNNING state are stopped and replaced
// according to the service's deployment configuration parameters,
// minimumHealthyPercent and maximumPercent . You can change the deployment
// configuration of your service using UpdateService .
// - If minimumHealthyPercent is below 100%, the scheduler can ignore
// desiredCount temporarily during task replacement. For example, desiredCount is
// four tasks, a minimum of 50% allows the scheduler to stop two existing tasks
// before starting two new tasks. If the minimum is 100%, the service scheduler
// can't remove existing tasks until the replacement tasks are considered healthy.
// Tasks for services that do not use a load balancer are considered healthy if
// they're in the RUNNING state. Tasks for services that use a load balancer are
// considered healthy if they're in the RUNNING state and are reported as healthy
// by the load balancer.
// - The maximumPercent parameter represents an upper limit on the number of
// running tasks during task replacement. You can use this to define the
// replacement batch size. For example, if desiredCount is four tasks, a maximum
// of 200% starts four new tasks before stopping the four tasks to be drained,
// provided that the cluster resources required to do this are available. If the
// maximum is 100%, then replacement tasks can't start until the draining tasks
// have stopped.
//
// Any PENDING or RUNNING tasks that do not belong to a service aren't affected.
// You must wait for them to finish or stop them manually. A container instance has
// completed draining when it has no more RUNNING tasks. You can verify this using
// ListTasks . When a container instance has been drained, you can set a container
// instance to ACTIVE status and once it has reached that status the Amazon ECS
// scheduler can begin scheduling tasks on the instance again.
