Switch monero-rpc to debug in tests
To be able to see CI monero RPC errors.

Workaround to avoid overflow in check_tx_key
`check_tx_key` can run into an overflow error when handling `-1` values for confirmations.
This most likely happens when a transaction is not in mempool yet.
In order to avoid unwanted side effects in the tests (i.e. failure because the transfer is seemingly confirmed, when it is not yet),
we add a guard that checks for values close to u64::MAX.
Note that we cannot check for the exact value of u64::MAX, because it seems that there is an addition somewhere in monerod/wallet-rpc,
that results in `-1` (first), `-2` (second) (...) until the transaction is in mempool.

Prefix for wallet-rpc container name for concurrent tests

387: Improve the resilience of the network layer r=thomaseizinger a=thomaseizinger

We improve the resilience in two ways:

1. Use a timeout on Bob's side for the execution-setup.
2. Use the `bmrng` library to model the communication between Alice and Bob.

See commit messages for details.

376: ASB resumes unfinished swaps after startup r=da-kami a=da-kami

Fixes #374 

- [x] Save Bob peer-id in database for Alice
- [x]  Alice: Wait for `10` Monero confirmations in `BtcRefunded` instead of `XmrLocked` (requires extending the RPC to distinguish locked / unlocked balance)
- [x] Save Alice peer-id in database for Bob ~~(+ multiaddress and remove params from resume)~~
- [ ] ~~Refactor Bob in test setup (handle event-loop in test setup similar to Alice)~~

I decided against refactoring Bob in the test setup, because eventually we might still want to add concurrent swap tests with multiple Bobs. The refactoring I had in mind would not allow such kind of tests. 
Generally, the current state of the changes already contains enough added value to open the PR :)

Follow ups out of scope

- [ ] Parametrize database with role (Alice / Bob) and remove all the (currently useless) mapping between DB and protocol types.
- [ ]  Alice: Wait for transfer proof ack before transitioning to new `XmrLocked`

Have --force flag only override the timelock check
It might very well be that the cancel transaction is already published.
If that is the case, there is no point in failing the command. We simply
transition to cancel and exit normally.

The reason this comes up now is because Alice now properly waits for
the cancel timelock as well and publishes the cancel transaction first.

Ultimately, she should not do that because there is no benefit to her
unless she can also publish the punish transaction.

Race sending transfer proof against cancel timelock
Sending the transfer proof might never resolve because Bob doesn't
come back online. In that case, we need to make sure we bail out
as soon as the timelock expires.

"Buffer" all requests to Alice until we are connected
We use the "precondition" feature of the `tokio::select!` macro to
avoid polling certain futures. In particular, we skip polling all
futures that - when resolved - require us to send a message to Alice.

Use bmrng to model communicaton of Alice's EventLoop with the handle
This allows us to delay the ACKing of the encrypted signature up until
the swap has actually requested it.

Similarly, it allows us to wait for the ACK of the transfer proof within
the swap before continuing.

1c47b32681
Use bmrng to model communicaton of Bob's EventLoop with the handle
bmrng is a library providing a request-response channel that allows
the receiving end of the channel to send a response back to the sender.
This allows us to more accurately implement the functions on the
`EventLoopHandle`. In particular, we now _wait_ for the ACK of specific
messages from the other party before resolving the future.

For example, when sending the encrypted signature, the async function
on the `EventLoopHandle` does not resolve until we received the ACK
from the other party.

We also delete the `Channels` abstraction in favor of directly creating
bmrng channels. This allows us to directly control the channel buffer
which we set to 1 because we don't need more than that on Bob's side.

Don't match on expired_timelocks and race it in a select in parallel
There is no point in first checking for the expired timelocks and
then constructing a `select!` that also watches for the timelock to
expiry.

We can simply only have the select! invocation to achieve the same
effect. In case the timelock is already expired, this future will
resolve immediately.

Normally, the polling order of `select!` is pseudo-random. We
configure it to be _biased_ here to make sure the futures are polled
in order.

Timeout Bob's execution-setup after 10 seconds
The execution setup is our only libp2p protocol that doesn't have
a timeout built-in. Hence, if anything fails on Alice's side, we
would wait here forever.

Wrapping the future in a timeout ensures that we fail eventually
if this protocol doesn't succeed.
