161: Introduce configuration file and initial setup through CLI r=da-kami a=da-kami
PRs chained on top of this one:
- [x] https://github.com/comit-network/xmr-btc-swap/pull/163 Configurable config with `--config` option on CLI (we will need this for swaps with ourselves...)
- [x] ~~https://github.com/comit-network/xmr-btc-swap/pull/165 Reset config with `--reset-config` option on CLI (this makes it easier for the user to clean up)~~
- [x] https://github.com/comit-network/xmr-btc-swap/pull/166 data-dir, in accordance to config-dir, should be pointed to the appropriate default directory using `directory-next`
Looks n' feel:

143: Upgrade to tokio 1.0 r=D4nte a=rishflab
When we were refactoring tests we realised we probably want the ability to abort a `tokio::JoinHandle` to kill the `EventLoop` to simulate a real world crash. tokio 1.0 is needed for this. It is probably about time to upgrade tokio anyway.
In order to upgrade to tokio 1.0 the following dependencies were also upgraded in the swap crate and monero-harness-rs
* backoff
* libp2p
* request
UPDATE: This should be merged until the following dependencies are uprgraded to Tokio 1.0 or Tokio compat is used
- [x] bitcoin-harness-rs https://github.com/coblox/bitcoin-harness-rs/pull/20

Alice was attempting to create a new event loop using the same listen addr as the old one which was still running. This commit aborts the event loop before creating a new one.
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
159: Introduce "one shots" r=D4nte a=D4nte
Instead of Alice sending messages to Bob by replying on a `RequestResponse` channel, she just acks reception on the channel and open her own channel to send messages to Bob.
This means we do not need to carry the channel around anymore and instead carry Bob's peer id.
We take this opportunity to rename messages as per the sequence diagram.
At this stage we only touch message 4 & 5 as they are the one shots messages of the protocol.
Decoupling message 4 from message 3 (still current called 2) will allow the introduction of an await/async behaviour that handles message 1, 2, 3.
To introduce message 1, 2, 3 we will introduced the async/await behaviour using https://github.com/comit-network/rust-libp2p-async-await
First, we need to upgrade tokio and libp2p.
Please note that thanks to this change, Alice now uses Bob's peer id to send message meaning that recovery is improved (as before we could not save the channel to the db).

As per the proposed changed in the sequence diagram.
The aim is to have a unique terminology per message instead of having
the same name for 2 consequent messages that share the same behaviour.
Note that the aim is to remove the shared `RequestResponse` behaviours.
