Properly handle concurrent messages to and from peers
Previously, we were forwarding incoming messages from peers to all
swaps that were currently running. That is obviously wrong. The new
design scopes an `EventLoopHandle` to a specific PeerId to avoid
this problem.

Make Monero and Bitcoin wallet use a generalized sync interval
We define the sync interval as 1/10th of the blocktime. For the
special case of our tests, we however check at max once per second.
The tests have a super fast blocktime. As such we shouldn't hammer
the nodes with a request every 100ms.

Disable timestamp if we log to a non-interactive terminal
A non-interactive terminal is likely something along the lines of
journalctl which captures a timestamp by itself. In theory, it could
also be just a logfile but we rather accept this limitation and keep
the configuration surface simple rather than exposing another config
switch.

Introduce Watchable abstraction for Bitcoin wallet
We have a repeated pattern where we construct one of our
Tx{Cancel,Redeem,Punish,Refund,Lock} transactions and wait until
the status of this transaction changes. We can make this more
ergonomic by creating and implementing a `Watchable` trait that
gives access to the TxId and relevant script for this transaction.
This allows us to remove a parameter from the `watch_until_status`
function.

Additionally, there is a 2nd pattern: "Completing" one of these
transaction and waiting until they are confirmed with the configured
number of blocks for finality. We can make this more ergonomic by
returning a future from `broadcast` that callers can await in case
they want to wait for the broadcasted transaction to reach finality.

Pass relevant execution params into wallet instead of via functions
The execution params don't change throughout the lifetime of the
program. They can be set in the wallet at the very beginning.
This simplifies the interface of the wallet functions.

Greatly reduce load onto the Electrum backend
We achieve our optimizations in three ways:

1. Batching calls instead of making them individually.

To get access to the batch calls, we replace all our
calls to the HTTP interface with RPC calls.

2. Never directly make network calls based on function
calls on the wallet.

Instead, inquiring about the status of a script always
just returns information based on local data. With every
call, we check when we last refreshed the local data and
do so if the data is considered to be too old. This
interval is configurable.

3. Use electrum's notification feature to get updated
with the latest blockheight.

ea05c306e0 Alice spawns swaps outside the event loop
Instead of spawning the swap inside the event loop we send the swap back
to the caller to be spawned. This means we no longer need the remote handle
that was only used in the tests.
This now properly logs the swap results in production.
It also gives us more control over Alice's swap in the tests.

https://github.com/da-kami/xmr-btc-swap/releases/tag/0.3-test

The asb ARM build does neither run tests on CI not smoke test for the binary upon release because the there is no standard runner for ARM. One can configure a self-hosted one but I think that might be an overkill: https://docs.github.com/en/actions/hosting-your-own-runners/adding-self-hosted-runners

I did download the produced ARM tar, unpack and test on the raspi, it works :)

Disable backoffs max_elapsed_time functionality
This config setting makes backoff stop retrying if we didn't get an
error within this timeframe.
For us, this results in backoff not actually doing anything.

The connection to kraken is very long-running. It might be active
for hours without failing. However, the default value for
`max_elapsed_time` is set to 15 minutes. As such, once the connection
fails any time after that, backoff doesn't actually retry the operation
but just gives up.

Fixes #303.

Refactor the kraken module to automatically re-connect on errors
In order to be able to re-connect on certain errors, we model
connection errors separately from parsing errors. We also change
the API of the whole module to no longer forward all errors to
the subscribers but instead, only update the subscribers with
either a latest rate or a permanent failure in case we exhausted
all our options to re-connect the websocket.

To model all of this properly, we introduce to sub-modules so that
each submodule can have their own `Error` type.

Resolves #297.

Merge #271
271: Bob can verify that the XMR lock tx was published r=da-kami a=da-kami

The Monero `txhash` log was removed. I feel the user should have the possibility to verify that the transaction was actually published so I added the tx-hash to the confirmation output. 

We could potentially print the tx-hash when receiving the transfer proof already, but that might not add much value compared to printing it with the confirmations. 

Additionally we should allow the user to at least know when the XMR can be expected in the user's wallet, otherwise the swap ends like this:

```
2021-03-04 13:49:19   INFO Monero lock tx received 5 out of 5 confirmations
```

This is just not very informative - yes, the final transaction is an implementation detail, but I don't think we should hide the transactions from the user. By printing the tx-hash for spending from the lock-tx into the user wallet we ensure the user knows that the XMR can now be expected in the user wallet.

47a31760c0 Bob can verify the Monero txs by tx-hash
Print tx-hashes for monero transactions to allow Bob to look the transaction up in block explorer.

The story of Bab:
Our famous actor Bob has a brother named Bab.
In school they were often mixed up, because their names were so similar.
Eventually Bab renamed himself into Barbara, but that was even more confusing for now he
carried a female name even though he was not female. Bob wanted to help his brother and told him he
could just go for Bub. But that did not solve anything. Fun fact: Bub is actually married to Alice.

Introduce quote protocol and display it to the user before they fund
Previously, the user neither knew the price nor the maximum quantity
they could trade. We now request a quote from the user and display
it to them.

Fixes #255.

Change imports_granularity to module
This reduces the overall amount of LoC that imports take up in our
codebase by almost 100.
It also makes merge-conflicts less likely because there is less
grouping together of imports that may lead to layout changes which
in turn can cause merge conflicts.

Merge #265
265: Replace quote with spot-price protocol r=thomaseizinger a=thomaseizinger

This is essentially functionally equivalent but includes some
cleanups by removing a layer of abstraction: `spot_price::Behaviour`
is now just a type-alias for a request-response behaviour.
