[Kata-hypervisor] Link to the Hypervisor Prototype

Folks, Please find below the link to the initial prototype code that tries to reduce the number of emulated devices in QEMU that can still boot most cloud workloads. https://github.com/intel/nemu We created some tooling around automated code reduction and a minimal CI to ensure that this code reduction still retained features that Linux expects to find when booting cloud images. https://github.com/intel/nemu/tree/master/tools https://github.com/intel/nemu/tree/master/tools/CI -manohar
