Add ResponseTimeCpuInterceptor to monitor response time and CPU usage per endpoint

[cfaur09]

Reasoning

• To monitor and log the response time and CPU usage for each endpoint in the application.
• To provide warnings when response time or CPU usage exceeds specified thresholds.
• To improve the observability and performance monitoring of the application.

Proposed Changes

• Added a new ResponseTimeCpuInterceptor to log response time and CPU usage for each endpoint.
• Configured the interceptor to log warnings if response time exceeds 1000ms or CPU usage exceeds 500ms.
• Integrated the interceptor globally in the application.

How to test

• Fast Endpoint:
  Make a request to a fast endpoint and verify that no warnings are logged.
• Slow Endpoint:
  Make a request to a slow endpoint and verify that warnings for response time and CPU usage are logged.
