Subject: [PATCH 3/6] Add test files for license header compliance testing

- Good files with complete license headers (4 files):
  * Java: TestProcessor.java
  * Python: setup-environment.py
  * YAML: docker-compose.yml
  * Properties: application.properties

- Bad files with missing/incomplete headers (5 files):
  * Java: NewFeature.java (no header)
  * Python: monitor.py (short header)
  * YAML: data-prepper-config.yaml (no header)
  * Properties: dev.properties (no header)
  * Shell: compile.sh (incomplete header)

These files test the license header compliance system across
all supported file types and various violation scenarios.

Subject: [PATCH 4/6] Fix license headers on all test files

Added complete license headers to all files that were flagged:
- data-prepper-core/src/main/java/org/opensearch/dataprepper/core/NewFeature.java
- tools/monitoring/monitor.py
- deployment/kubernetes/data-prepper-config.yaml
- config/environments/dev.properties
- scripts/compile.sh

All files now have the complete 5-line license header as required.
