RMQConnectionManager must be scoped to the child container

[derevnjuk]

When creating a repeater, we are currently reusing a global instance of RMQConnectionManager. This approach is causing unexpected behavior and may lead to potential issues.

Steps to Reproduce:

1. Create two repeaters using the RepeaterFactory.
2. Perform operations or actions on the repeater.

Expected Behavior:
The repeater should function correctly, using a scoped RMQConnectionManager instance specific to the repeater with the proper credentials.

Actual Behavior:
Due to the reuse of the global instance of RMQConnectionManager, the repeater may encounter unexpected behavior, such as incorrect handling of auth.
