> In the call path of {{Docker::inspect()}}, each continuation currently checks if {{promise->future().hasDiscard()}},
where the {{promise}} is associated with the output of the {{docker inspect}} call. However,
if the call to {{docker inspect}} becomes hung indefinitely, then continuations are never
invoked, and a subsequent discard of the returned {{Future}} will have no effect. We should
add proper {{onDiscard}} handling to that {{Future}} so that appropriate cleanup is performed
in such cases.
