Highlights from the Cloud Hypervisor release v16.0: 1) Improved live
migration support; 2) Improved `vhost-user` support; 3) ARM64 ACPI and
UEFI support; 4) Bug fixes.

Note: The client code of cloud-hypervisor's OpenAPI is automatically
generated by `openapi-generator` [1-2]. As the API changes do not
impact usages in Kata, no additional changes in kata's runtime are
needed to work with the current version of cloud-hypervisor.
