Picking peers weighted by the number of rare blocks they have. A block is rare if there are at most 2 copies in the neighborhood. Better number can be used (some function of neighborhood size)

Optimization: Master sends out at least one copy of each block first regardless of whatever a client is asking for. Once one copy of each block is out, Master then responds to specific blocks from individual receivers.

pickBlockRarestFirst and gossips commented OUT for now.
...
Problem with the rarestFirst implemention is that we are picking peers randomly first and then picking blocks from the random peer using rarestFirst. NOT the right away to do it. It should be the other way around.
Problem with gossip is that peers might end up overwriting newer information by older ones. To fix that we either have to have timestamps or must match the bitVectors before overwriting.

Fix in rarestFirst implemenation.
...
If there are more than one rarest blocks, pick randomly between them (was deterministic before)
