This removes warnings on `config.get`, where the `logging` configuration
key may also contain the current logging stream and we end up with a
JSONDecodeError when trying to serialize it.
The `disable_logging` attribute was only available on events and
responses, and it could only either entirely disable or enable logging
for all the events of a certain type.
The new flag allows more customization by setting the default logging
level used for any message of a certain type (or `None` to disable
logging). This makes it possible to e.g. set some verbose events to
debug level, and the user can see them if they configure the application
in debug mode.
It also delegates the logging logic to the message itself, instead of
having different parts of the application handling their own logic.
- More consistent naming for many methods, plus added a more extensive doc.
- Refactored the entry points for the daemon and the pusher into two
classes, easier to encapsulate and wrap into tests.
- Removed the local backend - managing the concurrency of two processes
reading and writing on the same socket at the same time was too much,
and its utility outside of the tests (which can have mock backends as
well) is quite modest.
- Managing stop events on the bus. Still some work to do tho.
- Fixed several bugs.
