Socket: ✏️ Heartbeat negotiation interceptor

[psychology50]

작업 이유

• Implement negotiation interceptor by STOMP
• Currently, there is an issue where the server follows the heartbeat value set by the client.

작업 사항

• When using external message broker, the negotiation process is handled by the broker, not by Spring
• But, the RabbitMQ STOMP Plugin doesn't support configuring server-side heartbeat
• So, I implemented an interceptor logic where the heartbeat negotiation is handled by Spring and then passed to RabbitMQ, which consistently follows the client's heartbeat setting.
