Correctly Implement Kademlia Rebalancing

[Stebalien]

When a DHT node finds a closer DHT node, it needs to forward DHT records.

@Stebalien I'd like to pick this up. Please can you give me some more background on the issue/point me to the part of the code I can dig deeper into ?

Warning: this is a difficult issue.

1. Read https://pdos.csail.mit.edu/~petar/papers/maymounkov-kademlia-lncs.pdf.
2. Re-read section 2.5.

Really, I don't recommend implementing this right now as we're not sure how it will effect the network.

[Stebalien]

The process is: Every hour, walk through all local DHT records. If we received the record within the last hour, skip it. Otherwise, call PutValue on it.

However, given the current performance of the DHT, this will likely cause more harm than good.

Is this a dup of #323?

[Stebalien]

Yes.
