Microservice pattern: Log deployments and changes #2696

Description:
The objective is to implement the Microservices - Log Deployments and Changes design pattern in our project. This pattern ensures that all deployments and changes to the microservices architecture are logged effectively. This enhances traceability, debugging, and auditing processes, making it easier to maintain the health and stability of the system.

Main elements of the pattern:

1. Centralized Logging System: Implement a centralized logging system to capture logs from all microservices. This helps in aggregating and analyzing logs from different sources in a unified manner.

2. Deployment Logging: Ensure that every deployment action is logged. This includes the timestamp, the service being deployed, version number, deployment environment, and the individual initiating the deployment.

3. Change Tracking: Log all changes made to the microservices, such as configuration changes, updates to service endpoints, and changes in inter-service communication protocols.

4. Automated Logging: Integrate logging into the CI/CD pipeline to automate the logging of deployment and change events, ensuring consistency and reducing manual intervention.

5. Visualization and Alerts: Provide tools to visualize logs and set up alerts for specific events or patterns, aiding in proactive monitoring and issue resolution.
