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.
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.
First, we tell the user that we are now waiting for Alice to lock
the monero. Additionally, we tell them once we received the
transfer proof which will lead directly into the
"waiting for confirmations" function.
291: Improve CLI help comments and "type" hints r=rishflab a=rishflab
The type hints are generated from the field names. This has the
unfortunate consequence of the config field becoming file_path which
does not really make sense people working on the codebase.
