continuous-integration/drone/push Build is passingDetails
1. Added documentation to the README on the possible options to run the
Redis service.
2. Show a relevant message to the user if the application is run with
`--start-redis` and Redis couldn't start.
3. Some LINT/black chores on some files that hadn't been touched in a
while.
The main application class has been moved from __init__ to the app
module.
__init__ will contain instead the relevant global variables and the
modules and objects exposed to external integrations - such as
`get_plugin` and `get_backend`, or the `main` itself.
This will make future integrations much easier - the global __init__
doesn't contain any business logic now, it can import anything without
fearing circular dependencies, and it can limit its exposed objects to
those that we want to expose to 3rd-party integrations and scripts.
It will also make it easier to extend the main entry point with
additional logic - such as a supervisor or an embedded Redis server.
