refactor Contact class, DHT RPCs, and Contact addition/removal
-track contact failures, last replied, and last requested. use this to provide a 'contact_is_good' property on Contact objects
-ensure no duplicate contact objects are created
-remove confusing conflation of node id strings with Contact objects, update docstrings
-move RPC failure tracking to a callback/errback pair in sendRPC (so the contact is only updated once)
-handle seed nodes during the join sequence by setting their node ids after they initially reply to our ping
-name all of the kademlia RPC keyword args, remove confusing **kwargs and dictionary parsing
-add host ip/port to DHT send/receive logging to make the results comprehensible when running many nodes at once

dht_node: split network start and join procedures
In order to attempt to join the DHT several times
(i.e. when the first attempt has failed) we need to
split the components initialization from the real
joining operation.

Create node.startNetwork() to initialize the node
and keep the rest in node.joinNetwork()

965969b856 Don't filter out local node ID when returning peer list
If a node is returning a peer list for a given blob hash
(being this been requested via CLI or via DHT) and it is
part of the resulting peer list, it will filter itself out
before returning the list.

This makes the results across the DHT inconsistent as
different nodes won't include themselves when
responding a findValue/findNode query.

Remove such filtering so that the local node ID is always
included when needed.

Extend close nodes list by right amount
When a k-bucket does not contain enough close nodes, the
DHT will look into neighbouring k-buckets in order to entend
the list of returned nodes.

However, the list should not be extended beyond its maximum size.
