Eliminated redundant `correlationId` tag setting. Adjusted `workflowInstance` and `activityInstance` tag schemas for better clarity. Simplified the processors list in `otel-collector-config.yaml`.
Renamed variables from 'activity' to 'span' for clarity and consistency. Added additional span tags for start and end times, status updates, and detailed error information for improved traceability and debugging.
Updated `docker-compose-datadog.yml` with new environment variables and updated image versions, enhancing trace sampling and service autodiscovery. Added Kubernetes deployment, service, and role files for `elsa-server`, `elsa-studio`, `plant-uml`, `postgres`, and `trace-lens`, improving the project's infrastructure. Enhanced OpenTelemetry middleware for better error handling and detailed tracing of activity and workflow executions.
This commit introduces the Elsa.OpenTelemetry module to provide OpenTelemetry sources for tracing workflow and activity execution. Additionally, it updates the program to include default workflow and activity execution pipelines with tracing middleware, and improves pipeline builder extensions to support middleware insertion.
