Roman Khimov 773ccc2b92 network: allow discoverer to reuse addresses
...and don't try to connect to the nodes we're already connected to.

Before this change we had a problem of discoverer throwing away good valid
addresses just because they are already known which lead to pool draining over
time (as address reuse was basically forbidden and getaddr may not get enough
new nodes).
