contrib: add torv3 seed nodes for testnet, drop v2 ones

laanwj commented at 2:30 pm on May 25, 2021: member

Replace the ancient (2015) Tor V2 hardcoded seeds with new Tor V3 ones. This needs to be done before 0.22 to make sure onion-only testnet nodes can still connect to the network. Continues #21560.

Ways to test:

Re-generate src/chainparamsseeds.h with cd contrib/seeds && python3 generate-seeds.py . > ../../src/chainparamsseeds.h, check if git tree stays the same.
Create a new testnet node with bitcoind -testnet -onlynet=onion -proxy=127.0.0.1:9050 (or delete ~/.bitcoin/testnet3/peers.dat), check if it is able to connect to the network and get blocks.
Check if the addresses are connectable for ex.:

0#!/usr/bin/env python3
1import subprocess
2with open('contrib/seeds/nodes_test.txt') as f:
3    for line in (line for line in (line.rstrip().split('#', 1)[0] for line in f) if line):
4        subprocess.call(["nc", "-v", "-x", "127.0.0.1:9050", "-z"] + line.split(':'))

Thanks to jonatack for providing the list.
