Fixes the issues that requests could not be sent from the host in Windows and Mac by binding the API to all the container interfaces instead of only localhost.
This may create issues with get_all_appointments, since it can only be called from inside the container. Not a big deal since that's more of a dev endpoint, but it'll
be nice to give it a fix eventually.
Key generation was performed using pyca/crpytography but keys were expected to be objects from coincurve. This comes from teos_cli where keys are generated beforehand and stored, and later on loaded from disk. The plugin generates keys and uses them straightaway (at least the first time), so it would fail in that case.
invalid_appointments in TowerInfo was used to stored invalid appointment responses from the tower when it was misbehaving (i.e. wrong or missing signature). However, a single item was stored since the tower is abandoned after misbehaving. data reported as invalid by the tower was not backed up.
invalid_appointments now stores the appointment rejected by the tower and reported as invalid.
misbehaving_proof stores the proof of misbehaviour by the tower (single item)
The previous approach was a bit messy with the db access and could have potential race conditions and data inconsistency
Also replaces format for f-functions for readability
- The appointment constructions is left in Watchtower (via on_commit_revocation method)
- The tower interaction is moved to net/http so it can be reused
- Adds missing logic for invalid resposes by the tower (e.g invalid signatures)
- Logs data identified by tower_id instead of endpoint
- Adds Retrier to deal with retries (for connection errors and rejects) and moves sending logic to net/http
- Adds pending appointments to TowerInfo and serves that information via `get_tower_info` and `list_towers`
- Deals with connection errors (but not with rejections yet)
