b4ceee49df Change monitoring to default wallet
The automated swap backend (asb) requires Monero funds, because Alice is selling Monero.
We use a hardcoded default wallet named asb-wallet. This wallet is opened upon startup.
If the default wallet does not exist it will be created.

a8bfc1d686 Make LatestRate::Error require std::error::Error trait bound
This allows us to use .context instead of .map_err when calling
`latest_rate()`. For the static rate module, we simply fill in
`Infallible` which is actually better suited because it describes
that we are never using this error.

b47b06aa23 Import anyhow::Result across the codebase
There is no need to fully qualify this type because it is a type
alias for std::Result. We can mix and match the two as we want.

644f4c1732 Bubble up ws error to consumer
Note that because we are using `watch` channel, only a reference to the
channel value can be returned.
Hence, using custom Error that can be cloned to be able to
pass `Result` through the channel.

Merge #209
209: Upgrade to bdk 0.4 r=thomaseizinger a=thomaseizinger

Effectively, this also means:

- Upgrading to rust-bitcoin 0.26
- Upgrading to miniscript 5
- Upgrading monero to 0.10
- Upgrading curve25519-dalek to 3
- Upgrading bitcoin-harness to rust-bitcoin 0.26 (https://github.com/coblox/bitcoin-harness-rs/pull/21)
- Upgrade `ecdsa_fun` to latest version
- Replace `cross_curve_dleq` with `sigma_fun` (to avoid an upgrade dance on that library)

I refrained from specifying `rev`s in the Cargo.toml because we have a lock-file anyway. This should allow us to update those dependencies easier in the future by just running `cargo update -p <dependency>`.

164de3c524 Properly calculate the confirmations for Bitcoin tx
Once the transaction was included into a block it has one confirmation - before inclusion it has zero.
current-block-height - transaction-block-height = zero; but that means one confirmation.
Hence, the confirmation calculation was adapted to: Current-block-height - (transaction-block-height - 1).

200: Wait for refund if insufficient Monero is locked up r=da-kami a=da-kami

In a scenario where Alice does not lock up sufficient funds Bob should properly transition to refunds. At the moment the CLI just panics. 
I noticed this when Alice accidentally had a different amount set than Bob. In the future this should not happen, because Alice provides the amount for Bob. However, in case Alice is malicious Bob should still transition correctly.

The default number of retries is 1. Unfortunately, the way this config
value is interpreted doesn't actually lead to a retry. We have to set
it to 2 to actually make it retry.

a0ef1f96ec Replace bitcoind wallet with bdk wallet
The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.

Remove acknowledgements processing
We are aware of issues of timeouts when waiting for acknowledgements.
Also, to properly supports acks in a multiple swap context, we need to
revert to doing event processing on the behaviour so that we can link
leverage the `RequestResponse` libp2p behaviour and link the messages
requests ids to swap ids when receiving an ack or response.

Acks are usefully for specific scenarios where we queue a message on the
behaviour to be sent, save as sent in the DB but crash before the
message is actually sent. With acks we are able to resume the swap,
without ack, the swap will abort (refund).

Allow EventLoop to hold a database ready to pass to alice::Buider
The `EventLoop` will use the `Builder` interface to instantiate a
`Swap` upon receiving a `SwapRequest` and successfully doing an
execution setup.
Before this change, the `EventLoop` would have to hold the path to the
db and re-open the db everytime it wants to construct a swap.

With this change, we can open the DB once and then hold a
`Arc<Database>` in the `EventLoop` and pass it to new `Swap`s structs.

Restart event loop in tests
Alice was attempting to create a new event loop using the same listen addr as the old one which was still running. This commit aborts the event loop before creating a new one.

Upgrade tokio to 1.0
Upgrade bitcoin harness dependency to latest commit

Upgrade backoff to fix failing tests. The previous version of backoff had a broken version of the retry function. Upgraded to a newer comit which fixes this problem.

Upgrade hyper to 0.14 as the 0.13 was bringing in tokio 0.2.24

Upgraded bitcoin harness to version that uses tokio 1.0 and reqwest 0.11

Upgrade reqwest to 0.11. Reqwest 0.11 uses tokio 1.0

Upgrade libp2p to 0.34 in preparation for tokio 1.0 upgrade

149: Fix Alice redeem scenario r=da-kami a=da-kami

Follow up of #144, partial fix of https://github.com/comit-network/xmr-btc-swap/issues/137

 Fix Alice redeem scenario

- 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)

Use builder terminology instead of factory
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.

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

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.
