RabbitMQ is not used properly

[maxi07]

Currently the RabbitMQ connection does work, but the program keeps rebuilding connections. Normally you would establish a connection once and keep it alive.
I would need

• Unified handling of RabbitMQ communication across services
• Establish RabbitMQ connection once, then keep it alive
