-- Cancels the specified Capacity Reservation, releases the reserved
-- capacity, and changes the Capacity Reservation\'s state to @cancelled@.
--
-- Instances running in the reserved capacity continue running until you
-- stop them. Stopped instances that target the Capacity Reservation can no
-- longer launch. Modify these instances to either target a different
-- Capacity Reservation, launch On-Demand Instance capacity, or run in any
-- open Capacity Reservation that has matching attributes and sufficient
-- capacity.
