-- increase the size, the group schedules actions to create new instances
-- using the current instance template. If you decrease the size, the group
-- schedules delete actions on one or more instances. The resize operation
-- is marked DONE when the resize actions are scheduled even if the group
-- has not yet added or deleted any instances. You must separately verify
-- the status of the creating or deleting actions with the
-- listmanagedinstances method.
