since we import rust discv5 from sigp, this pr modifies the discv4 code. discv4 now drops nodes in
Neighbours
responses that are already connected in discv5. it verifies this by access to a mirror of keys in discv5's kbuckets, that is updated, if needed, when discv4 receives aNeighbours
message. the goal is to ensure any two nodes are connected over discv5 xor discv4, preferring discv5. nodes are identified by their node id, so to make this possible, nodes use the same secret key in discv4 and discv5. closes #1383.also moves poll function in
