Disable backoffs max_elapsed_time functionality
This config setting makes backoff stop retrying if we didn't get an
error within this timeframe.
For us, this results in backoff not actually doing anything.

The connection to kraken is very long-running. It might be active
for hours without failing. However, the default value for
`max_elapsed_time` is set to 15 minutes. As such, once the connection
fails any time after that, backoff doesn't actually retry the operation
but just gives up.

Fixes #303.

Refactor the kraken module to automatically re-connect on errors
In order to be able to re-connect on certain errors, we model
connection errors separately from parsing errors. We also change
the API of the whole module to no longer forward all errors to
the subscribers but instead, only update the subscribers with
either a latest rate or a permanent failure in case we exhausted
all our options to re-connect the websocket.

To model all of this properly, we introduce to sub-modules so that
each submodule can have their own `Error` type.

Resolves #297.

Tell the user more about the monero lock transaction
First, we tell the user that we are now waiting for Alice to lock
the monero. Additionally, we tell them once we received the
transfer proof which will lead directly into the
"waiting for confirmations" function.

Move error message on sync _into_ the function
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.

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.

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.
