317: Fix monero refresh interval r=thomaseizinger a=thomaseizinger

The comparison should be the MAXIMUM of the two values, not the
minimum, otherwise we always refresh at an interval of 1 second.

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.

Fix env filter for asb
1. The asb didn't log any if the statements within main.rs
2. We were initializing unnecessary filters that don't make any sense
for the asb. warp and http are not used and the harness-es are for
test only.

318: Alice spawns swaps outside the event loop r=thomaseizinger a=da-kami

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.

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.

Eliminate build_bitcoin_punish_transaction

314: Remove CLI config file in favour of parameters r=thomaseizinger a=da-kami

The CLI has sensible default values for all parameters,
thus a config file is not really an advantage but just
keeps getting in our way, so re remove it.

311: Add asb to release including ARM build r=da-kami a=da-kami

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 :)

305: Disable `backoff`s `max_elapsed_time` functionality r=da-kami a=thomaseizinger

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.
