[Enhancement] Integrate Prometheus and Grafana for monitoring in playground

[orenccl]

Description:
To improve the project's observability and monitoring capabilities, it is suggested to integrate Prometheus and Grafana into the playground environment. This would enable easier monitoring of various application metrics.

Objectives:

• Prometheus: For collecting and storing application metrics.
• Grafana: For visualizing data collected by Prometheus, providing the team with real-time monitoring dashboards.

Implementation Approach:

• Add Prometheus and Grafana configurations within the Docker environment.
• Set up basic metrics collection, such as application request rate, response time, etc.

I would like to take on this task. I'll start by setting up Prometheus and Grafana within the Docker environment and configuring the basic metrics collection as described. Please let me know if there are any specific requirements or guidelines you'd like me to follow.
