> Looks like decommissioning a node (nodetool decommission) will stream all the non-system
table data out to it's appropriate peers (StorageService.unbootstrap()), but hints will disappear
with the node. Let's send those hints to another peer (preferably in the same rack, and hopefully
at least the same datacenter) them to be replayed.
> The use case here is auto-scaling vnode clusters in ec2. When auto-scaling down, I'd
want to call decommission on the node to leave the ring (and be terminated), and still have
all of it's artifacts (data and hints) survive.
