Peer searching improvements #64

Closed matjazv closed 1 year ago

matjazv commented 1 year ago

What was the problem?

This PR resolves #47.

How was it solved?

Bootstrap was introduced which automatically connects to a seed peers if number of connections drop below configured number.
Unused lists of peers/IPs were removed from peerbook.
Timeout was added when connecting to a peer in peer.go.
It's possible to configure different TTLs for libp2p's peerstore.
Peer exchange was enabled for all peers and not only for seed peers.

How was it tested?

New unit tests were implemented.
Existing and new unit tests passed.

I have moved BlacklistedPeers() to peer.go because I see it there to be more appropriate place for it.

I have also removed some checks from peer.Connect() function because connectionGater handles all that.
