This way, we are co-locating the type with the expression that requires it.
This makes it easier to take this expression and compose it with other ones
without having to touch the type hint on the variable.

Container initialization and wallet initialization have to ensure to use the same wallet name.
In order to avoid problems constants are introduced to ensure we use the same wallet name.
Prefixing docker-containers and -networks is a necessity to be able to spin up multiple containers and networks.
However, there is no reason to prefix the wallet names that live inside a container. One cannot add a wallet with
the same name twice, so the prefixing of wallets does not bring any advantage. When re-opening a wallet by name
the wallet name prefix is cumbersome and was thus removed.
The wallet is an instance of a wallet that has a name.
When we use `CreateWalletForOutputThenReloadWallet` we actually unload the wallet.
It would be cleaner to create a new instance that does that swap, but I did not go that far.
264: Untangle Bob's `EventLoop` from the `Builder` r=thomaseizinger a=thomaseizinger
This is work towards #255.

Instead of instantiating the `EventLoop` within the builder, we only
pass in the necessary arguments (which is the `EventLoopHandle`) to
the Builder upon `new`.
This is work towards #255 which will require us to perform network
communication (which implies having the `EventLoop`) before starting
a swap.
If our expression directly evaluates to a future, we don't need to
create an async block.
This requires us to have `EventLoopRun::run` consume the instance
instead of just taking a mutable reference (otherwise we run into
lifetime issues). However, that is better anyway because `run` is
an endless loop so you never get to use the handle afterwards
anyway.

253: Monero rpc installer for windows r=rishflab a=rishflab
I could not find an async zip archive extractor. The download is still async. One potential follow up could be to spawn the extraction of the zip in the windows path.
Closes#228

Previously we were ignoring if the monero wallet rpc was not found and
unpacked from archive leading to a failure down the line when trying to
run a non-existent executable. Bail when the executable is no found in
the archive.
248: Wait for wallet to catch up instead of block generation r=thomaseizinger a=da-kami
The monero harness wallet always starts a miner that mines new blocks every second.
This can conflict with additionally triggering block generation and cause this error:
```
monero_rpc::rpc::monerod: generate blocks response: {
"error": {
"code": -7,
"message": "Block not accepted"
},
"id": "1",
"jsonrpc": "2.0"
}
```
See error in CI run here: https://github.com/comit-network/xmr-btc-swap/runs/2001131193
Since the miner is generating blocks anyway we can wait for the wallet to catch up.
Refresh is done upon querying the balance, thus the refresh calls were removed.
---
Note: we could also opt for starting the miner optionally. This would make this test more efficient, but is a more intrusive change, thus I opted for this fix for now.

1. We can generalize the signing interface by passing a PSBT in
instead of the `TxLock` transaction.
2. Knowing the transaction ID of a transaction that we are about
to sign is not very useful. Instead, it is much more useful to know
what failed. Hence we add a `.context` to the call of `sign_and_finalize`.
3. In case the signing succeeds, we will immediately broadcast it
afterwards. The new broadcasting interface will tell us that we broadcasted
the "lock" transaction.
We eliminate unnecessary layers of indirection for broadcasting logic
and force our callers to provide us with the `kind` of transaction
that we are publishing.
Eventually, we can replace this string with some type-system magic
we can derive the name from the actual transaction. For now, we just
require the caller to duplicate this information because it is faster
and good enough TM.
This struct is a wallet. The only thing it can meaningfully broadcast
are transactions. The fact that they have to be signed for that is
implied. You cannot broadcast unsigned transactions.
Abstracting over the individual bits of functionality of the wallet
does have its place, especially if one wants to keep a separation
of an abstract protocol library that other people can use with their
own wallets.
However, at the moment, the traits only cause unnecessary friction.
We can always add such abstraction layers again once we need them.
If the user doesn't pass `--debug`, we only show `INFO` logs but
without time and level to make it clearer that it is meant to be
read by the user.
Without `--debug`, the user sees:
Still got 0.00009235 BTC left in wallet, swapping ...
With `--debug`, they see:
2021-03-01 12:21:07 DEBUG Database and seed will be stored in /home/thomas/.local/share/xmr-btc-swap
2021-03-01 12:21:07 DEBUG Starting monero-wallet-rpc on port 40779

Previously, the time was formatted as ISO8601 timestamps which is
barely readable by humans. Activating the `chrono` feature allows
us to format with a different format string. The output now looks
like this:
2021-03-01 11:59:52 DEBUG Database and seed will be stored in /home/thomas/.local/share/xmr-btc-swap
2021-03-01 11:59:52 DEBUG Starting monero-wallet-rpc on port 40673

There is a double space after the time which is already fixed in
tracing-subscriber but not yet released.
See https://github.com/tokio-rs/tracing/issues/1271.
Log messages are ideally as close to the functionality they are talking about, otherwise we might end up repeating ourselves on several callsites or the log messages gets outdated if the behaviour changes.
