Optimize CI/CD build times - Integration tests timing

[cicoyle]

The CI/CD pipeline is experiencing timeouts during integration tests, specifically for Spring Boot 3.3.9. The build job Build jdk:17 sb:3.3.x exp:false is being cancelled after exceeding the 30-minute execution limit, as seen in this failed run.

Current State

• Integration tests are taking longer than 30 minutes to complete
• The workflow includes resource-intensive operations, for ex:
  • Docker container setup (MongoDB, Kafka)
  • Dapr CLI and runtime initialization
  • Complex workflow testing with external dependencies
• Tests run sequentially without parallelization

Proposed Solutions

Parallel Test Execution

• Enable Maven Surefire parallel execution for unit tests
• Configure Maven Failsafe for parallel integration tests
• Add parallel module building with -T flags

Split Workflow Strategy

• Separate unit tests from integration tests into different jobs
• Run unit tests first and in parallel
• Only run integration tests (in parallel) after unit tests pass
• Use focused timeouts for each job type

Test Optimization

• Review and optimize slow integration tests

Expected Benefits

• Reduce overall build time by ~30-50%
• Eliminate timeout issues
• Improve developer experience with faster feedback at PR time
• Reduce CI/CD resource usage

Acceptance Criteria

• Build completes within reasonable time (< 20 minutes)
• All existing tests continue to pass
• No regression in test coverage
• Maintainable and clear CI/CD configuration
