-- Creates or updates a managed scaling policy for an Amazon EMR cluster.
-- The managed scaling policy defines the limits for resources, such as EC2
-- instances that can be added or terminated from a cluster. The policy
-- only applies to the core and task nodes. The master node cannot be
-- scaled after initial configuration.
