p2p/discover: move bond logic from table to transport (#17048) * p2p/discover: move bond logic from table to transport This commit moves node endpoint verification (bonding) from the table to the UDP transport implementation. Previously, adding a node to the table entailed pinging the node if needed. With this change, the ping-back logic is embedded in the packet handler at a lower level. It is easy to verify that the basic protocol is unchanged: we still require a valid pong reply from the node before findnode is accepted. The node database tracked the time of last ping sent to the node and time of last valid pong received from the node. Node endpoints are considered verified when a valid pong is received and the time of last pong was called 'bond time'. The time of last ping sent was unused. In this commit, the last ping database entry is repurposed to mean last ping _received_. This entry is now used to track whether the node needs to be pinged back. The other big change is how nodes are added to the table. We used to add nodes in Table.bond, which ran when a remote node pinged us or when we encountered the node in a neighbors reply. The transport now adds to the table directly after the endpoint is verified through ping. To ensure that the Table can't be filled just by pinging the node repeatedly, we retain the isInitDone check. During init, only nodes from neighbors replies are added. * p2p/discover: reduce findnode failure counter on success * p2p/discover: remove unused parameter of loadSeedNodes * p2p/discover: improve ping-back check and comments * p2p/discover: add neighbors reply nodes always, not just during init
