The type hints are generated from the field names. This has the
unfortunate consequence of the config field becoming file_path which
does not really make sense people working on the codebase.
The bitcoin::Wallet::sync_wallet function doesn't do anything else
other than delegating. As such, we have just as much information
about what went wrong inside this function as we have outside.
By moving the .context call into the function, we can avoid repeating
us on every call-site.
288: Switch to public stagenet node that works r=rishflab a=rishflab
The xmr.to node has been unreliable lately. The exan.tech node seems to
working.
@da-kami is following up with making this configurable. Lets get this in so we can get a release on Friday.

Instead of leaking the tokio::sync:⌚:Receiver type in our
return value, we create a newtype that implements the desired
interface. This allows us to get rid of the `RateService` structs
and instead implement `LatestRate` directly on top of this struct.
Given that `LatestRate` is only used within the event_loop module,
we move the definition of this type into there.
271: Bob can verify that the XMR lock tx was published r=da-kami a=da-kami
The Monero `txhash` log was removed. I feel the user should have the possibility to verify that the transaction was actually published so I added the tx-hash to the confirmation output.
We could potentially print the tx-hash when receiving the transfer proof already, but that might not add much value compared to printing it with the confirmations.
Additionally we should allow the user to at least know when the XMR can be expected in the user's wallet, otherwise the swap ends like this:
```
2021-03-04 13:49:19 INFO Monero lock tx received 5 out of 5 confirmations
```
This is just not very informative - yes, the final transaction is an implementation detail, but I don't think we should hide the transactions from the user. By printing the tx-hash for spending from the lock-tx into the user wallet we ensure the user knows that the XMR can now be expected in the user wallet.

Print tx-hashes for monero transactions to allow Bob to look the transaction up in block explorer.
The story of Bab:
Our famous actor Bob has a brother named Bab.
In school they were often mixed up, because their names were so similar.
Eventually Bab renamed himself into Barbara, but that was even more confusing for now he
carried a female name even though he was not female. Bob wanted to help his brother and told him he
could just go for Bub. But that did not solve anything. Fun fact: Bub is actually married to Alice.
Previously, the user neither knew the price nor the maximum quantity
they could trade. We now request a quote from the user and display
it to them.
Fixes#255.
This reduces the overall amount of LoC that imports take up in our
codebase by almost 100.
It also makes merge-conflicts less likely because there is less
grouping together of imports that may lead to layout changes which
in turn can cause merge conflicts.
265: Replace quote with spot-price protocol r=thomaseizinger a=thomaseizinger
This is essentially functionally equivalent but includes some
cleanups by removing a layer of abstraction: `spot_price::Behaviour`
is now just a type-alias for a request-response behaviour.

Please review by commit :)
Did a few cleanups before actually doing the feature.

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.
