The fact that we have the rendezvous behaviour composed into the ASB behaviour and handle all events in one eventloop is not optimal. It would be nice if we can handle rendezvous completely separate.
This command uses a rendezvous node to find sellers (i.e. ASBs) and query them for quotes.
Sellers, that can be dialed and queried for a quote will be listed.
585: Configurable kraken websocket url via the ASB config r=thomaseizinger a=cimble-code
- Allows the ASB operator to configure a custom kraken websocket url via the ASB config.
- Addresses the issue of price control first brought up [here](https://github.com/comit-network/xmr-btc-swap/discussions/571)
> Gotya.
There is a relatively easy to implement (but temporary) solution for that. We could let the user configure the kraken websocket url via the ASB config. That way you can plug in your own service. The only requirement is that your service publishes prices updates in the same format as [kraken](https://docs.kraken.com/websockets/), e.g. :

Some network and application specific code does not belong in the protocol module and was moved.
Eventloop, recovery and the outside behaviour were moved to the respective application module because they are application specific.
The `swap_setup` was moved into the network module because upon change both sides will have to be changed and should thus stay close together.
Having `spot_price` and `execution_setup` as separate protocols did not bring any advantages, but was problematic because we had to ensure that `execution_setup` would be triggered after `spot_price`. Because of this dependency it is better to combine the protocols into one.
Combining the protocols also allows a refactoring to get rid of the `libp2p-async-await` dependency.
Alice always listens for the `swap_setup` protocol. When Bob opens a substream on that protocol the spot price is communicated, and then all execution setup messages (swap-id and signature exchange).

535: Bitcoin network check when building PSBT r=da-kami a=da-kami
This ensures that funds are not sent to an address on the wrong network.

Since we introduced our own parsing function for command line arguments, we have to make sure that clap's behaviour is handled correctly.
Clap's `get_matches_from_safe` returns an error of a certain kind, of which `ErrorKind::HelpDisplayed` and `ErrorKind::VersionDisplayed ` have to be handled to properly print the help/version and exit the program.
The clap error includes the message, so we print help/version in main now and ensure the program exits with `0` afterwards.
By default the finality confirmations of the network's `env::Config` will be applied and no finality confirmations will be persisted on disk in the config file.
It is however possible to set finality confirmations in the config file for bitcoin and monero for power users at their own risk.
If set the defaults will be overwritten with the parameter from the config file upon startup.
To run the ASB on testnet, one actively has to provide the `--testnet` flag.
Mainnet and testnet data and config are separated into sub-folders, i.e. `{data/config-dir}/asb/testnet` and `{data-dir}/asb/mainnet`.
The initial setup is also per network. If (default) config for the network cannot be found the initial setup is triggered.
Startup includes network check to ensure the bitcoin/monero network in config file is the same as the one in the `env::Config`.
Note: Wallet initialization is done with the network set in the `env::Config`, the network saved in the config file is just to indicate what network the config file is for.
This includes testing CLI commandline args
Clap's `default_value_with` actually did not work on `Subcommand`s because the parent's flags were not picked up.
This was fixed by changing parameters dependent on testnet/mainnet to options.
This problem should have been detected by tests, that's why the command line parameter tests were finally (re-)added.
Thanks to @rishflab for some pre-work for this.
In order to allow people to plug into public nodes / be more flexible with their own setup we now enforce specifying the monero daemon port to be used by the `monero-wallet-rpc`.
In the past we had problems with flags/parameter changes several times, where on instance was changed, buy another one was missed. This should mitigate this problem.
This patch introduces structs for all duplicated parameters and uses flatten to only have one point for changes.
Additionally removes all mentions of `alice` from the commands / variables. This code is on an application level and should not be concerned with swap protocol roles.
Introduces a minimum buy Bitcoin amount similar to the maximum amount already present.
For the CLI the minimum amount is enforced by waiting until at least the minimum is available as max-giveable amount.
Max-buy and spread is not something that one would configure on every run.
More convenient to keep this in the config.
The max-buy Bitcoin value was adapted to `0.02` which is more reasonable for mainnet.
Activated feature `serde-float` to serialize the spread (Decimal) as float instead of string.
```
...
[maker]
max_buy_btc = 0.02
ask_spread = 0.02
```
Adds `cancel`, `refund`, `punish`, `redeem` and `safely-abort` commands to the ASB that can be used to trigger the specific scenario for the swap by ID.
In the production code it is a weird indirection that we load the state and then pass in the state and the database.
In the tests we have one additional load by doing it inside the command, but loading from the db is not expensive.
Move Alice's spot price logic into a dedicated network behaviour that handles all the logic.
The new behaviour encapsulates the complete state necessary for spot price request decision making.
The network behaviour cannot handle asynchronous calls, thus the balance is managed inside the spot price and has to updated regularly from the outside to ensure the spot price balance check has up to date data.
At the moment the balance is updated upon an incoming quote requests.
Code that is relevant for both ASB and CLI remains in the `network::spot_price` module (e.g. `network::spot_price::Error`).
