704: Allow withdrawing and viewing of the bitcoin balance on swap-cli r=rishflab a=devbordecraft
Same mechanics of the ASB but on swap-cli as discussed in #694
Co-authored-by: devbordecraft <devbordecraft>
Previously, we relied on the wallet in the `monero-wallet-rpc` daemon
to be loaded as we do on startup. As a consequence of this expectation,
restarting `monero-wallet-rpc` to fix bugs like #652 resulted in the
ASB no longer operating correctly.
To fix this, we now load the wallet on-demand in case the daemon responds
with the error code -13.
Ideally, we would implement this behaviour generically using the proxy
pattern on the `MoneroWalletRpc` trait. Unfortunately, when attempting
to do so we uncover a limitation in the design of `jsonrpc_client`.
This limitation is tracked in https://github.com/thomaseizinger/rust-jsonrpc-client/issues/47.
Once fixed, we can implement this logic in a more robust way that is not
tied to the `check_tx_key` RPC call but applies to any RPC call automatically.
Instead of splitting up the transports into capabilities, we compose
them directly for each application. This allows us to remove the
websocket transport for the CLI which is really only needed for the
ASB to allow retrieval of quotes via the browser.
Adds the ping behaviour to both ASB and CLI behaviour that periodically pings a connected party to ensure that the underlying network connection is still alive.
This fixes problems with long-running connections that become dead without a connection closure being reported back to the swarm.
This improves the error handling on the ASB.
Once the Bitcoin redeem transaction is seen in mempool, the state machine cannot transition to a cancel scenario anymore because at that point the CLI will have redeemed the Monero.
The additional state then waits for transaction finality.
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`.
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.
When a CLI requests a spot price have some errors that are expected, where we can provide a proper error message for the CLI:
- Balance of ASB too low
- Buy amount sent by CLI exceeds maximum buy amount accepted by ASB
- ASB is running in maintenance mode and does not accept incoming swap requests
All of these errors returns a proper error to the CLI and prints a warning in the ASB logs.
Any other unexpected error will result in closing the channel with the CLI and printing an error in the ASB logs.
Resume-only is a maintenance mode where no swaps are accepted but unfinished swaps are resumed.
This is achieve by ignoring incoming spot-price requests (that would lead to execution setup) in the event-loop.
Using the same default directory as data-/config-dir has caused unwanted side effects when running both applications on the same machine.
Use these directory names:
- ASB: xmr-btc-swap/asb
- CLI: xmr-btc-swap/cli
Since the functionality is now application specific the respective functions were moved into the appropriate module of the application.

This PR does a few things.
* It adds a TorTransport which either dials through Tor's socks5 proxy or via clearnet.
* It enables ASB to register hidden services for each network it is listening on. We assume that we only care about different ports and re-use the same onion-address for all of them. The ASB requires to have access to Tor's control port.
* It adds support to dial through a local Tor socks5 proxy. We assume that Tor is always available on localhost. Swap cli only requires Tor to be running so that it can send messages via Tor's socks5 proxy.
* It adds a new e2e test which swaps through Tor. For this we assume that Tor is currently running on localhost. All other tests are running via clear net.
