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.
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.
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.
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.
In order to ensure that we can atomically generate_from_keys and then reload a wallet,
we have to wrap the client of the monero wallet RPC inside a mutex.
When introducing the Mutex I noticed that several inner RPC calls were leaking to the
swap crate monero wallet. As this is a violation of boundaries I introduced the traits
`GetAddress`, `WalletBlockHeight` and `Refresh`.
Note that the monero wallet could potentially know its own public view key and
public spend key. If we refactor the wallet to include this information upon wallet
creation we can also generate addresses using `monero::Address::standard`.
Upgrade bitcoin harness dependency to latest commit
Upgrade backoff to fix failing tests. The previous version of backoff had a broken version of the retry function. Upgraded to a newer comit which fixes this problem.
Upgrade hyper to 0.14 as the 0.13 was bringing in tokio 0.2.24
Upgraded bitcoin harness to version that uses tokio 1.0 and reqwest 0.11
Upgrade reqwest to 0.11. Reqwest 0.11 uses tokio 1.0
Upgrade libp2p to 0.34 in preparation for tokio 1.0 upgrade
Rust fmt automatically groups the imports (from top to bottom) as `pub use` `use crate` and `use`.
There is no need to introduce sections which cause annoyance when auto importing using the IDE.
Created network, storage and protocol modules. Organised
files into the modules where the belong.
xmr_btc crate moved into isolated modulein swap crate.
Remove the xmr_btc module and integrate into swap crate.
Consolidate message related code
Reorganise imports
Remove unused parent Message enum
Remove unused parent State enum
Remove unused dependencies from Cargo.toml
