-- Set the instance affinity value for a specific stopped instance and
-- modify the instance tenancy setting.
--
-- Instance affinity is disabled by default. When instance affinity is
-- 'host' and it is not associated with a specific Dedicated host, the next
-- time it is launched it will automatically be associated with the host it
-- lands on. This relationship will persist if the instance is
-- stopped\/started, or rebooted.
--
-- You can modify the host ID associated with a stopped instance. If a
-- stopped instance has a new host ID association, the instance will target
-- that host when restarted.
--
-- You can modify the tenancy of a stopped instance with a tenancy of
-- 'host' or 'dedicated'.
--
-- Affinity, hostID, and tenancy are not required parameters, but at least
-- one of them must be specified in the request. Affinity and tenancy can
-- be modified in the same request, but tenancy can only be modified on
-- instances that are stopped.
