> Currently time to live for stored hints is hardcoded to be gc_grace_seconds. 
> This causes problems for applications using backdated deletes as a form of 
> optimistic locking. Hints for updates made to the same data on which delete 
> was attempted can persist for days, making it impossible to determine if 
> delete succeeded by doing read(ALL) after a reasonable delay. We need a way 
> to explicitly configure hint TTL, either through schema parameter or through 
> a yaml file.
