Summary

As a support engineer for the logging operator, I want to enable debug log level for vector to better troubleshoot issues.

Acceptance Criteria

• Verify vector log level can be set to debug
• Verify `VECTOR_LOG` environment variable is set in the collector pod
• Verify upstream documents are updated to identify feature

Notes

• Log level can be one of: trace, debug, info, warn, error, off.
• Possible annotation: "observability.openshift.io./log-level": "<SOME LOG LEVEL>"
