Previously the libp2p swarm had to be manually polled within the
protocol execution code to execute actions such as sending a
message. The swarm is now wrapped in SwarmDriver which polls the
swarm in a seperate task
Tracing should be initialized by test and the `_guard` kept alive within the test.
Re-using this code in different tests does not really have any additional value.
Instead of specifying what messages we want to include, I went for a filter that excludes noise.
That way we get more useful logging.
Use reusable test init functions for happy path test
Extract tracing setup to reusable function
Move test initialization to seperate functions
Increase stack size in CI
Fix monero max finality time
Force Bob swarm polling to send message 2
Run Bob state to xmr_locked in punish test to force the sending of
message2. Previously Bob state was run until btc_locked. Although
this was the right thing to do, message2 was not being sent as the
swarm was not polled in btc_locked. Alice punish test passes.
Add info logging to executor
This introduces a lot of duplication between the binary and the
library, but it's okay because this module should only be a temporary
measure until we allow recovery to be handled by the original state
machine.
Also, fix a bug in `xmr_btc::alice::action_generator` caused by the
incorrect assumption that Alice's ability to punish Bob could be
determined before the cancel transaction hits the blockchain.
Also use cosntant backoff retry strategy as opposed to exponential
backoff. This is in case retrying several times quickly causes the
retry intervals to become large enough that the test is very slow
and/or the Bitcoin lock transaction expires.
The current problem occurs on the last message i.e. Bob sending
tx_redeem_encsig to Alice. The action is yielded for Bob to do it, but
Alice appears to never receive it (unconfirmed claim, requires more
logging).
