- Properly check the timelocks before trying to redeem
- Distinguish different failure scenarios and reactions to it.
- if we fail to construct the redeem transaction: wait for cancel.
- if we fail to publish the redeem transaction: wait for cancel but let the user know that restarting the application will result in retrying to publish the tx.
- if we succeed to publish the tx but then fail when waiting for finality, print error to the user (secreat already leaked, the user has to check manually if the tx was included)
This is not really a factory as a factory design pattern is about
producing several instances.
In the current usage, we are only interested in one swap instance. Once
the swap instance is created, the factory becomes useless. Hence, it is
more of a builder pattern.
Currently this code is actually not reachable, but that is semantically applied by the program's flow (the resume command includes the swap direction).
It is still preferred to have an error message rather than an unreachable statement.
- Introduce Test abstraction instead of tow harnesses, move test specific data into Test
- Change the abstraction from actors to swap, because we are creating swaps, not actors
- rename actor::swap to run, because we are running a swap
145: Make lock-tx id available in redeem/punish state to be able to assert exact fees r=da-kami a=da-kami
We can do exact assertions for Bob's redeem as well, but have to store Bob's tx_lock id in the respective final state. Make tx_lock available in BtcRedeemed and BtcPunished to have better assertions / harmonize test behaviour.
Storing this information is strictly speaking not needed for the production environment. But it is static information that can be seen as additional information that can be handy for a user. We could potentially extract it inside the tests as well (for redeem without restart would be a bit tricky), but I think this solution is more elegant.

144: Test refactor r=da-kami a=da-kami
This PR is pure refactoring, keeping the logic of the tests we had before. No production code is touched besides re-exports in early commits (no logic changes).
In the follow ups improvements will be introduced, that touch the production code as well.
All remaining tasks actioned since Friday:
- [x] `happy_path_bob _restart` (trivial)
- [x] add refund assertions to harnesses (trivial)
- [x] convert all refund scenarios currently being tested (trivial)
- [x] remove dead test init code once all old tests are converted
- [ ] ~~(optional) move alice and bob harness code into separate files~~ -> might action this once re-using test code in production.
Out of scope, follow up:
- [x] https://github.com/comit-network/xmr-btc-swap/pull/145 - We can do exact assertions for Bob's redeem as well, but have to store Bob's `tx_lock` id in the respective final state. Make `tx_lock` available in `BtcRedeemed` and `BtcPunished` to have better assertions / harmonize test behaviour.
- [ ] update the production code to use the `Alice` and `Bob` structs to bundle the params - update tests to use the production struct.
- [ ] Re-use test swap setup in production (i.e. `Alice-/BobHarness::new`) to setup the swap.
- [ ] add additional tests
- [ ] re-try moving the tests from `test` to `src` (if the peer_id was the only problem this should be trivial now - but should be done after the refactor is finished)
- [ ] creating new wallets upon restart
- [ ] aborting the old event loop after restart

136: Testnet resume fixes r=da-kami a=da-kami
Add a few log statements on Bob's side to make the user experience better.
Update / remove ToDos.
I set the log level to `Info` in main again, `Debug` heavily clutters the output. In order to make `Debug` more usable we might want to review printing all those `rpc` messages. But this goes beyond the scope of this PR.

This makes the redeem assertion reusable for all tests with a redeem scenario.
Since the factory was not a clean factory before and is now doing even more it was renamed to harness.
