run testnet with HAfAH on CI
There are some test scenarios which can't be tested by pattern tests, like checking correctness of reversible data (not included in any block_log yet). We need nodes in live sync to check this.
We can quickly setup testnets by using test_tools and we have test scenarios on hive CI (and also haf CI) for testnet builds. It would be good to add some scenarios also with HAfAFH instance connected.
