Pull Request Overview
This PR adds support for setting a file mode for container content mounts by updating the YANG model and implementing the corresponding logic in the container processing code.
- Updated YANG module with a new revision and added the "mode" leaf with an octal string pattern.
- Modified the container creation logic in C to parse the mode value and apply it using fchmod.
- Updated the module reference and ChangeLog to reflect the new feature.

Using the file name (nm) directly in a shell command via snprintf could allow command injection if nm contains unexpected characters. Consider sanitizing nm or using a safer method to decode base64 content without invoking a shell.
