HCP Packer now tracks CI/CD pipeline metadata

HCP Packer now supports tracking CI/CD pipeline metadata, allowing users to see which tools were used in the image-building process through integrations with GitHub and GitLab. This enhancement helps lay the foundation for a secure build pipeline and grants HCP Packer level 1 compliance with SLSA (Supply-Chain Levels for Software Artifacts). The addition of pipeline metadata tracking improves build visibility, providing critical CI/CD information such as pipeline IDs, job names, details on the operating system, VCS commits, and more. This helps organizations make risk-based security decisions and shift their security left in the infrastructure deployment process.
