-- Schedules a group action to delete the specified instances in the
-- managed instance group. The instances are also removed from any target
-- pools of which they were a member. This method reduces the targetSize of
-- the managed instance group by the number of instances that you delete.
-- This operation is marked as DONE when the action is scheduled even if
-- the instances are still being deleted. You must separately verify the
-- status of the deleting action with the listmanagedinstances method.
