Rework Discord Service #61
Description
The Discord service needs to be initialized lazy. In the current implementation, this means that at some point in time, the service is just half-way initialized.
Also, over the past months, Serenity released updates. The way we use Serenity at the moment is deprecated.
- Use some sort of state management (State pattern or a simple state enum) to switch between uninitialized or fully initialized
- Read through the updated Serenity docs and adapt to the way shown there
