Improve Component Metrics Collection and Add Log Collection

## Motivation  

- Although metrics collection has been added for components like manager and agent, only general metrics are being collected, which are insufficient for comprehensive service analysis.
- There are metrics to track the execution results after receiving requests, but no metrics are being collected for the client layer that makes requests to other components.
- While Prometheus metrics are being collected, logs cannot be easily tracked.

## Objective  

- Collect Prometheus metrics for Redis, Etcd, and DB requests.
- Collect RPC Server in agent component.
- Enable easy log visualization and collection.

## Expected Sub Issue

- Register Fluent Bit and Kibana for log collection and visualization.
- Add Prometheus metrics for Redis, Etcd, DB requests and RPC server.
