490: Mainnet switch r=da-kami a=da-kami
Fixes #446Fixes#360Fixes#506Fixes#478
To be precise: It is actually a testnet switch, because I think mainnet should be default.
I took several assumptions on the way (e.g. network support, ...).
At this stage any feedback welcome :)
TODO:
- [ ] successful mainnet swap with this code base before merging :)
Co-authored-by: Daniel Karzel <daniel@comit.network>
It is currently not expected that ASB and CLI are used for swaps > 10_000$ equivalent to XMR/BTC, thus the finality confirmations were reduced to an equivalent of 20 mins of work (2 blocks for Bitcoin, 10 for Monero).
Monero enforces 10 unlocking blocks until the balance is spendable, so the finality confirmations cannot be set lower than 10.
We subscribe to transactions upon broadcast, where we use output index `0` for the subscription.
In order to ensure that this subscription is guaranteed to be for the locking script (and not a change output) we now ensure that the locking script output is always at index `0` of the outputs of the transaction.
We chose this solution because otherwise we would have to add more information to broadcasting a transaction.
This solution is less intrusive, because the order of transaction outputs should not have any side effects and ensuring index `0` makes the whole behaviour more deterministic.
The Electrum block-header subscription did not provide us with block headers, because upon the connection being closed by a node the subscription would end.
Re-newing the the subscription upon re-connect is not easily achievable, that's why we opted for a polling mode for now, where we start a block header subscription on every update iteration, that is only used once (when the subscription is made).
There is no `--mainnet` flag.
Since we cannot just pass an empty string to `.arg()` we use the `.args()` method to pass nothing for mainnet and the respective flags for stagenet and testnet.
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.
486: Update metadata and remove outdated config files / READMEs r=thomaseizinger a=thomaseizinger
508: Remove tokio-tar from workspace in favor of git dependency r=thomaseizinger a=thomaseizinger
Fixes#315.
Fixes#227.
The upstream PR that upgrades to tokio v1 got merged, hence we can at least point to the git dependency for now and remove that later once it has been released to crates.io

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.
493: Add checks to max_giveable amount. r=da-kami a=bonomat
We need to check two things:
- balance to be higher than dust amount (546).
- balance to be higher than min-relay fee.
Additionally, the tx_builder might fail if not enough funds are in the wallet to pay for the overall transaction fees. In both cases, we return 0.

474: Add more log details r=bonomat a=bonomat
Resolves#448
1. The first commit adds an additional log statement of the exchange rate for each state-update. This is useful because it allows us to measure profitability easily, i.e. by knowing what was the exchange rate when the swap was started and what was it when it was finalized.
2. The second commit changes a bunch of log messages.
3. The third commit is adds a new commandline flag to toggle json format.
