closes: #5127 #5036 peers that are overwhelmed or generally will not be used for requests. there are two criteria used to select good peer: - request success rate . success rates within 0.1 (10%) of each other are treated as equal, and in such case we will use latency - latency. hs/1 protocol used to track latency, as it is the most used protocol and objects served in this protocol are of the same size with several exceptions (active sets, list of malfeasence proofs). related: #4977 limits number of peers to request data for atxs. previously we were requesting data from all peers atleast once. synced data 2 times in 90m, previous attempt on my computer was 1 week ago and took 12h
