GSoC 2025: add an idea for Lima

[AkihiroSuda]

Lima

VM plugin subsystem

• Description: Lima (https://lima-vm.io) is a project that provides Linux virtual machines with a focus on running containers.
  Lima supports several VM backends via built-in drivers: qemu, vz (Apple Virtualization.framework), and wsl2 (see lima/pkg/driverutil/instance.go).
  The idea for GSoC is to make a plugin subsystem that decouples the built-in VM drivers into separate binaries that communicate with the main Lima binary via some RPC (probably gRPC).
  This idea will improve the maintainability of the code base, and also help supporting additional VM backends (e.g., vfkit and cloud-based drivers).
• Expected Outcome:
  • Design the plugin subsystem and its RPC (probably gRPC)
  • Migrate the existing built-in VM drivers to the new plugin subsystem
  • Implement additional VM plugins if the time allows
• Recommended Skills: Go, gRPC, QEMU, macOS
• Expected project size: medium (~175 hour projects)
• Mentor(s):
  • Akihiro Suda (@AkihiroSuda) - primary
  • Anders Björklund (@afbjorklund)
• Upstream Issue (URL): Add framework for adding new drivers at runtime, for instance for cloud lima-vm/lima#2007

@afbjorklund, could you also approve or 👍 this PR to confirm your participation.

@AkihiroSuda, could you update this PR to take care of the merge conflicts? (Please put Lima in alphabetical order with the rest of the projects).
