-- Deregisters the specified task definition by family and revision. Upon
-- deregistration, the task definition is marked as 'INACTIVE'. Existing
-- tasks and services that reference an 'INACTIVE' task definition continue
-- to run without disruption. Existing services that reference an
-- 'INACTIVE' task definition can still scale up or down by modifying the
-- service\'s desired count.
--
-- You cannot use an 'INACTIVE' task definition to run new tasks or create
-- new services, and you cannot update an existing service to reference an
-- 'INACTIVE' task definition (although there may be up to a 10 minute
-- window following deregistration where these restrictions have not yet
-- taken effect).
