8bf467b550 Make the factory code usable in production
- 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

Merge #145
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.

Bob has to check for the possibility to cancel in every state after he locked the BTC.
Otherwise Bob will try to perform actions that don't have any point and it might be impossible to use the `resume` command because it will always fail in trying to go on with Alice even though that might not be possible.

As Bob is dialing Alice, we now ensure that we are connected to Alice
at each step that needs communication.
If we are not connected, we proceed with dialing.

In an attempt to improve libp2p usage, we also add known address of
Alice first and only use peer_id to dial.
This ensures that we use the expected peer id.

98: Remove tor module r=da-kami a=da-kami

This removes the currently unused `tor module`.
Different `tokio` versions have been causing issues with the `tor` module in the past (i.e. `Cargo.lock` broken problem...). It started causing issues again when adding a dependency to `jsonrpc_client` working on https://github.com/comit-network/xmr-btc-swap/pull/97

We don't support `tor` at the moment and are no planning to add this feature initially as it is not super important to users. 
The functionality can easily added again at a later point.

Delete bob::negotiate
This module was intended to contain helper functions for each step.

However, those are not needed except for the negotiate step.
A dedicated module is not needed for one function.

Add a TODO to use existing helper functions
Helper functions already exist on the xmr-btc crate states, use them
like it is done in the bob module.

Remove passing alice peer id
The usage of the peer id is incorrect as we do not even check it when
dialing. For now, we can ignore it.
We can then re-introduce it and use it properly at a later stage.
