runtime-rs: Add basic CH implementation
Add a basic runtime-rs `Hypervisor` trait implementation for Cloud Hypervisor (CH). > **Notes:** > > - This only supports a default Kata configuration for CH currently. > > - Since this feature is still under development, `cargo` features have > been added to enable the feature optionally. The default is to not enable > currently since the code is not ready for general use. > > To enable the feature for testing and development, enable the > `cloud-hypervisor` feature in the `virt_container` crate and enable the > `cloud-hypervisor` feature for its `hypervisor` dependency. Fixes: #5242. Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>
