Redo layout of eventloop module
1. Move internal types to the bottom and make them private
2. Sort public types by their importance

Provide stronger isolation of kraken module
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.

Merge #271
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.

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.

This reduces the overall amount of LoC that imports take up in our

It also makes merge-conflicts less likely because there is less
grouping together of imports that may lead to layout changes which

2bb1c1e177 No prefix for wallets in monero harness
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.

9f53dab3c6 Harmonize names to make more sense
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.

Decouple Bob's EventLoop from the builder
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.

Don't unnecessarily create async blocks
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.

Reduce logging when signing transactions
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.

Unify logging of broadcasted transactions
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

Remove traits in favor of using the wallet struct directly
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.

Only show _log_ output if the user passes --debug
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:
