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.

Better dht shutdown.
...
The old code relied on the timing of DelayedCalls
to see what had been called or not, but unfortunately
we don't have a real-time OS so the timing on DelayedCalls
can only be approximate. Changed to explicitly keep
track of which calls had been made.
This simplifies the shutdown logic drastically, and I believe
we can take out the reactor.iterate() now
