Add support for block-based rootfs of Linux based workloads on top of cloud-hypervisor. Furthermore, update the documentation to explicitly mention the support for cloud-hypervisor and provide the necessary information about it in all the necessary pages.
Previously, only the "VMM/Sandbox" support page was mentioning about cloud-hypervisor.
