Major refactoring done across several files in the src/modules directory. This includes simplifying complex sections of code, removing extraneous comments, and improving the clarity of existing comments. In addition, method names and certain variable names were updated to more accurately reflect their function.
AzureServiceBusOption.cs and RabbitMqOptions.cs files were removed as they're no longer needed. The system now defers the configuration of MassTransit and AzureServiceBus to the application layer (Program.cs). The configuration for PrefetchCount is also allowed at the transport-level. A new abstraction, ConsumerTypeDefinition, collects all the consumer types with their respective definitions if provided. Adjustments have been made in related extension methods and classes to reflect these changes.
