Bob does not care whether tx lock is confirmed. That is alice's problem.
This wait was introduced to remedy a bug in status_of_script() which was
failing when called on a transaction with no confirmations.
320: Fix env filter for asb r=thomaseizinger a=thomaseizinger
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.

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.

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.

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.

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.
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.
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.

We reduce indirection by constructing TxPunish directly based off
`State3` and make the type itself more powerful by moving the logic
of completing it with a signature onto it.
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.
This allows us to have access to RedeemTx from within the scope
of the state transition which we are going to need for more
efficient watching of what happens to this TX on the blockchain.
313: Bump tracing-subscriber to 0.2.17 r=da-kami a=thomaseizinger
This release includes a bug-fix that removes an erroneous space
from our logs when running with `--debug`.

314: Remove CLI config file in favour of parameters r=thomaseizinger a=da-kami
Fixes#282
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.

306: Fix logging and retrying of Monero transaction watching r=thomaseizinger a=thomaseizinger
Hopefully, this should also reduce the load because I am not asking the node every second.

Instead, we use a regular loop and extract everything into a function
that can be independently tested.
`backoff` would be useful to retry the actual call to the node.
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.

301: Refactor the kraken module to automatically re-connect on errors r=thomaseizinger a=thomaseizinger
Co-authored-by: Thomas Eizinger <thomas@eizinger.io>
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.
