f8848aca55 Describe additional state for ToDo that might cause trouble 
If we wait for lock transaction confirmations immediately after sending the transaction without saving this state to the DB this might cause locking the money twice.
An additional state is needed for such a scenario.

Remove overzealous clippy overrides 
We have overridden a number of clippy warnings such as
"large enum variant".

Considering that we have a number of issues
 with the stack size in CI, it is more prudent to follow clippy's advice
 and box larger items so that the enum does not take larger space.

Do note that an instance of the enum always takes as much space as its
largest variant.

Merge #107 
107: Ensure that Bob can cancel correctly if T1 expired and Alice did not … r=da-kami a=da-kami

Bob has to check for the possibility to cancel in every state after he locked the BTC.
Otherwise Bob will try to perform actions that don't have any point and it might be impossible to use the `resume` command because it will always fail in trying to go on with Alice even though that might not be possible.

Bob refunds swap after restart that requires communication 
As Bob is dialing Alice, we now ensure that we are connected to Alice
at each step that needs communication.
If we are not connected, we proceed with dialing.

In an attempt to improve libp2p usage, we also add known address of
Alice first and only use peer_id to dial.
This ensures that we use the expected peer id.

Merge #98 
98: Remove tor module r=da-kami a=da-kami

This removes the currently unused `tor module`.
Different `tokio` versions have been causing issues with the `tor` module in the past (i.e. `Cargo.lock` broken problem...). It started causing issues again when adding a dependency to `jsonrpc_client` working on https://github.com/comit-network/xmr-btc-swap/pull/97

We don't support `tor` at the moment and are no planning to add this feature initially as it is not super important to users. 
The functionality can easily added again at a later point.

Previously Alice was trying to redeem after receiving the encsig
without checking if t1 had elapsed.

f5d3d54b13 Prevent premature Bob t1 timeout 
Bob was hitting the t1 timeout and entering cancel
instead of redeem. This was resolved by increasing
the timeouts to 50.

27d1334726 Init Alice behaviour with state0 
Previously state0 had to be set after creating Alice's behaviour.
With the event loop we no longer has access to the swarm so
set_state0() has to be called indirectly through a channel. This
means it is difficult to guarantee state0 is being set due to the
asynchronous nature of channels. This was solved by initialising
Alice with state0.

6f7408ecce Drive swarm in seperate async task 
Previously the libp2p swarm had to be manually polled within the
protocol execution code to execute actions such as sending a
message. The swarm is now wrapped in SwarmDriver which polls the
swarm in a seperate task

1a2857af29 Properly init tracing per test and reverse the filter to be exclusive 
Tracing should be initialized by test and the `_guard` kept alive within the test.
Re-using this code in different tests does not really have any additional value.

Instead of specifying what messages we want to include, I went for a filter that excludes noise.
That way we get more useful logging.
