a51194b9fa Instantiate electrum client with custom config with 2 retries
The default number of retries is 1. Unfortunately, the way this config
value is interpreted doesn't actually lead to a retry. We have to set
it to 2 to actually make it retry.

See https://github.com/bitcoindevkit/rust-electrum-client/issues/47.

180e778df9 Allow blockchain calls to fail
Prior to this change, functions could not fail early on permanent errors eg. parsing a url. Merged error enums.

a0ef1f96ec Replace bitcoind wallet with bdk wallet
The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.

Merge #190
190: Do not pass Monero amount to the CLI r=D4nte a=D4nte

The CLI user only pass the Bitcoin amount they want to sell.

The CLI then do a quote request to nectar which provides the Monero amount the taker can get.

188: Tor cleanup r=da-kami a=da-kami

We never removed Tor install from CI. I don't think it should be necessary given that Tor was removed in code.

Only pass btc amount to CLI

Also align terminology with the sequence diagram.

To allow the related timelock to be defined with the

Give a more specific name to the CLI binary: swap-cli
The current binary name is very generic `cli`. `swap-cli` better
describes what this binary does.

needs to be passed before a command.

No evident added value of having separate Seed structs
Hence, reducing complexity of the codebase. Note that the seed will be
used by both nectar and the cli whereas the config mod will be different
so this changes helps with the next step of having a dedicated config
module for each binary.

Remove punish test
The punish test needs re-work due to the fact that Alice runs continuously

Currently focusing on the CLI (Bob), so we can re-introduce this test
once we want to ensure that nectar (Alice) punishes.

Remove Bob restart tests after communication
The test do not work without acks as we stop the event loop as soon
as a message is considered as "sent" when actually the event loop
and swarm may not have yet sent the message.

The ack allow to avoid this issue as the message was considered "sent"
only once the other party sent a response. However, the ack brings
other issue so a review needs to be done to select the appropriate
solution.

Remove acknowledgements processing
We are aware of issues of timeouts when waiting for acknowledgements.
Also, to properly supports acks in a multiple swap context, we need to
revert to doing event processing on the behaviour so that we can link
leverage the `RequestResponse` libp2p behaviour and link the messages
requests ids to swap ids when receiving an ack or response.

Acks are usefully for specific scenarios where we queue a message on the
behaviour to be sent, save as sent in the DB but crash before the
message is actually sent. With acks we are able to resume the swap,
without ack, the swap will abort (refund).

Remove unnecessary channels
`alice::swap::run_until` will be called once the execution setup is
done. The steps before are directly handled by the event loop,
hence no channels are needed for said steps: connection established,
swap request/response & execution setup.

Prepare separation of event loop initialisation to swap initialisation
As for Alice, the event loop will be started with the program and will
be the one starting swaps (`run_until`) based on libp2p events (swap
request).

Allow EventLoop to hold a database ready to pass to alice::Buider
The `EventLoop` will use the `Builder` interface to instantiate a
`Swap` upon receiving a `SwapRequest` and successfully doing an
execution setup.
Before this change, the `EventLoop` would have to hold the path to the
db and re-open the db everytime it wants to construct a swap.

With this change, we can open the DB once and then hold a
`Arc<Database>` in the `EventLoop` and pass it to new `Swap`s structs.
