Description

Cassandra supports disabling the hints or reducing the window for hints.
It would be helpful to have a switch which stops hints to a down data center but continue hints to other DCs.
This is helpful during data center fail over as hints will put more unnecessary pressure on the DC taking double traffic. Also since now Cassandra is under reduced reduncany, we don't want to disable hints within the DC.
