EnvFilter is applied globally. This means you cannot log at INFO level
to the terminal and at DEBUG level to log files. To get a around this
limitation I had to implement the layer trait on a new type and filter
in the on_event() trait method. Each swap has its own log file denoted
by its swap_id. The logger appends to the existing file when resuming a
swap.

396: Remove default connection details from CLI r=thomaseizinger a=rishflab
Connecting buyers to us by default is not consistent with our vision of
a decentralised network of sellers.

It might very well be that the cancel transaction is already published.
If that is the case, there is no point in failing the command. We simply
transition to cancel and exit normally.
The reason this comes up now is because Alice now properly waits for
the cancel timelock as well and publishes the cancel transaction first.
Ultimately, she should not do that because there is no benefit to her
unless she can also publish the punish transaction.
This allows loading the seller-peer-id from the database upon resuming a swap.
Thus, the parameters `--seller-peer-id` is removed for the `resume` command.
Other than the peer-id the multi address of a seller can change and thus is
still a parameter. This parameter might become optional once we add DHT support.
The swap should not be concerned with connection handling. This is
the responsibility of the overall application.
All but the execution-setup NetworkBehaviour are `request-response`
behaviours. These have built-in functionality to automatically emit
a dial attempt in case we are not connected at the time we want to
send a message. We remove all of the manual dialling code from the
swap in favor of this behaviour.
Additionally, we make sure to establish a connection as soon as the
EventLoop gets started. In case we ever loose the connection to Alice,
we try to re-establish it.
351: Show the actual BTC amount and fee to be swapped r=da-kami a=da-kami
We got user feedback, that it is confusing that the amount "found" in the wallet does not match the amount actually being swapped, thus with this PR we explicitly display the amount swapped and fees.

Since Alice's refund scenario starts with generating the temporary wallet
from keys to claim the XMR which results in Alice' unloading the wallet.
Alice then loads her original wallet to be able to handle more swaps.
Since Alice is in the role of the long running daemon handling concurrent
swaps, the operation to close, claim and re-open her default wallet must
be atomic.
This PR adds an additional step, that sweeps all the refunded XMR back into
the default wallet. In order to ensure that this is possible, Alice has to
ensure that the locked XMR got enough confirmations.
These changes allow us to assert Alice's balance after refunding.
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.

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.
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.
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.
There are no refund timelock, only a cancellation timelock and punish
timelock.
Refund can be done as soon as the cancellation transaction is published.
As Bob is dialing Alice, we now ensure that we are connected to Alice
at each step that needs communication.
If we are not connected, we proceed with dialing.
In an attempt to improve libp2p usage, we also add known address of
Alice first and only use peer_id to dial.
This ensures that we use the expected peer id.
The usage of the peer id is incorrect as we do not even check it when
dialing. For now, we can ignore it.
We can then re-introduce it and use it properly at a later stage.
Previously state0 had to be set after creating Alice's behaviour.
With the event loop we no longer has access to the swarm so
set_state0() has to be called indirectly through a channel. This
means it is difficult to guarantee state0 is being set due to the
asynchronous nature of channels. This was solved by initialising
Alice with state0.
Consolidate and simplify swap execution. Generators are no longer
needed. Consolidate recovery and swap data structures. The
recursive calls can be replaced with a loop if returning prior to
completion is desired for testing purposes.
