Avoid the 32-second "try to connect to some nodes" construct.

Instead:

• Split the peer slots into three parts:
  • Reserved (peers that have been passed by the --reserved flag - they get their own special slots and should be continuously, though responsibly, (re)connected to)
  • Outgoing (number of slots == min_peers, these are connections to nodes that we discover/remember and initiate)
  • Incoming (number of slots == max_peers - min_peers, these are inbound connections from nodes that have discovered us)

Regarding Outgoing peers:

• We start by connecting to up to min_peers nodes; they each take a slot in our Outgoing peer table.
• We attempt to connect to a (/the highest scoring, once reputation system is done) node when one of the following happens:
  • A previous connection to a node has failed.
  • A peer who was in the Outgoing table has been/become disconnected.
  • We have discovered new nodes and have slots free in the Outgoing peer table.
  • The backoff timer of a previous node has expired and we can retry connecting.
