Pull request overview
This PR introduces a new image manager component for handling OCI (Open Container Initiative) image layers within the SM (Service Manager) module. The implementation provides functionality for unpacking layer archives, calculating directory digests, and determining unpacked layer sizes.
Key Changes:
- Added ImageHandler class with methods for layer unpacking, size calculation, and digest computation
- Refactored common utilities: renamed
HashDirtoCalculateDirDigestfor better clarity and extractedChangeOwnerinto a reusable utility function - Extended OCI spec support to handle rootfs configuration in image configs
