How Has This Been Tested?

Pull request overview

This PR updates OS Image Composer’s template and RPM package-resolution capabilities to support wildcard package patterns and repo-priority–based candidate selection, while also updating several PTL-related Ubuntu/EMT templates to include additional packages and repository pinning updates.

Changes:

• Add glob/wildcard support for RPM package filtering and requested package expansion, with additional resolver test coverage.
• Introduce repository-priority–aware selection for multi-candidate RPM dependency resolution.
• Update the image template JSON schema and example templates to use allowPackages and permit glob patterns in package lists.
