Alice's spot price logic into dedicated behaviour
Move Alice's spot price logic into a dedicated network behaviour that handles all the logic.
The new behaviour encapsulates the complete state necessary for spot price request decision making.
The network behaviour cannot handle asynchronous calls, thus the balance is managed inside the spot price and has to updated regularly from the outside to ensure the spot price balance check has up to date data.
At the moment the balance is updated upon an incoming quote requests.

Code that is relevant for both ASB and CLI remains in the `network::spot_price` module (e.g. `network::spot_price::Error`).

Move messages into protocol module
This allows us to remove all visibility modifiers from the message
fields because child modules (in this case {alice,bob}::state) can
always access private fields of structs.

It also moves the messages into a more natural place. Previously,
they were defined within the network layer even though they are
independent of the libp2p implementation.

Unify transfer-proof protocol to a single one
Previously, we had two implementations of this protocol. To reduce
code size, we make Alice and Bob use the same implementation.

Inline wait_for_bitcoin_refund
This function is essentially a single select! statement and can
easily be inlined into the swap state machine.

Change imports_granularity to module
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.

Replace quote with spot-price protocol
This is essentially functionally equivalent but includes some
cleanups by removing a layer of abstraction: `spot_price::Behaviour`
is now just a type-alias for a request-response behaviour.

Prepare separation of event loop initialisation to swap initialisation
As for Alice, the event loop will be started with the program and will
be the one starting swaps (`run_until`) based on libp2p events (swap
request).

Allow EventLoop to hold a database ready to pass to alice::Buider
The `EventLoop` will use the `Builder` interface to instantiate a
`Swap` upon receiving a `SwapRequest` and successfully doing an
execution setup.
Before this change, the `EventLoop` would have to hold the path to the
db and re-open the db everytime it wants to construct a swap.

With this change, we can open the DB once and then hold a
`Arc<Database>` in the `EventLoop` and pass it to new `Swap`s structs.

Move generation of keys inside State0::new

Restart event loop in tests
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 tokio to 1.0
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

Rename bob::Message2 to Message5
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.

44c4b5dcea Remove newlines from import statements to avoid problems
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.

Use builder terminology instead of factory
This is not really a factory as a factory design pattern is about
producing several instances.

In the current usage, we are only interested in one swap instance. Once
the swap instance is created, the factory becomes useless. Hence, it is
more of a builder pattern.

41e335fc2d Error messages instead of unreachable
Currently this code is actually not reachable, but that is semantically applied by the program's flow (the resume command includes the swap direction).
It is still preferred to have an error message rather than an unreachable statement.
