Description
The way stream tasks are calculated currently is quite inefficient, improve that.
Also, we currently try to distribute the streaming nodes evenly, this creates many more sstables than necessary - instead we should try to stream everything from a single peer, this should reduce the number of sstables created on the out-of-sync node.
