Connection Pool Tasks

[DanMacDonald]

Connection Tasks

1. Define the maximum number of connections in the local nodes connection pool (based on bandwidth / median block size)
2. Subsample the address list and attempt to handshake / establish connections with nodes
3. Record the latency of handshakes and score peers accordingly
4. If a peer falls below the reputation_threshold, drop the connection.
5. Reserve 20% of the connection pool for new / no reputation connections (so new peers can join the network)
6. Repeat subsampling and reputation scoring until the local connection pool is saturated or there are no unvisited addresses in the address_table to attempt to connect with.

(also record the latest block height from the /info data of each peer)
