WIP : Add support for IncludeOS

[shivansh-source]

This PR adds comprehensive support for IncludeOS, a unikernel framework written in C++ designed for building web and cloud applications, to the urunc container runtime. IncludeOS can execute on top of both solo5 (hvt/spt) and qemu hypervisors, making it a natural addition to urunc's growing unikernel ecosystem.

📋 Changes Made

pkg/unikontainers/unikernels/includeos.go - IncludeOS
pkg/unikontainers/unikernels/unikernel.go - Factory
README.md - Added IncludeOS to supported platforms table
docs/index.md - Updated support matrix
docs/unikernel-support.md - Full IncludeOS documentation
docs/hypervisor-support.md - Added IncludeOS hypervisor reference
docs/Sample-images.md - Added sample image documentation
tests/e2e/test_cases.go - Added Qemu-includeos and Hvt-includeos test cases

New Features

• IncludeOS Unikernel Implementation:
  • Created pkg/unikontainers/unikernels/includeos.go implementing the full Unikernel interface
  • Support for network configuration (IPv4 with gateway and subnet mask)
  • Support for block device management
  • Compatible with both Solo5 (hvt/spt) and QEMU hypervisors

Implementation Details

1. Core Unikernel Struct (includeos.go)

type IncludeOS struct {
    Command string           // Command line arguments
    Monitor string           // Hypervisor type (qemu, hvt, spt)
    Net     IncludeOSNet     // Network configuration
    Block   []IncludeOSBlock // Block devices
}

How was this tested?

• Built an IncludeOS application with CMake
• Packaged as a Docker container with urunc labels
• Tested with urunc runtime:

  docker save includeos-sample:latest | sudo ctr -n k8s.io images import -
  sudo ctr -n k8s.io run --rm --runtime io.containerd.urunc.v2 docker.io/library/includeos-sample:latest test

Result: Successfully outputs "Hello, world!"
Test Repository
github.com/shivansh-source/includeos-sample
Docker Image

Pull command:
docker pull shivansh1111/includeos-sample:latest

Closes #126

Hello @shivansh-source ,

if a PR is WIP then you can mark it as draft. The approach is the same for all guests in urunc. The important thing is to test it. Please take a look at #540 and use it a as a guide.

@cmainas tested and added proper testing methods . ready for review
