Fix Issue with RabbitMQ Message Consumption

This update addresses two key issues related to message consumption from RabbitMQ:

1. Goroutine Management for Output Channel:
   Currently, when a message is received from RabbitMQ, it is passed to the output channel using a goroutine. This results in a new goroutine being created for every message. Once the output channel reaches its buffer limit, all the goroutines are blocked, waiting for space in the channel to send the messages. This update optimizes the message handling to prevent unnecessary goroutine buildup.

2. Set Prefetch Count to Match Output Channel Buffer:
   RabbitMQ, by default, fetches all messages at once unless a prefetch count is specified. To avoid overwhelming the system with too many messages at once, we have set the RabbitMQ prefetch count to match the buffer size of the output channel. This ensures that only a manageable number of messages are fetched and processed at a time.
