largest vcpu number is limited to defaultMaxQemuVCPUs.
Here, a new helper is introduced in pkg/katautils/config.go to get

This commit add option "enable_guest_swap" to config hypervisor.qemu.
It will enable swap in the guest. Default false.
When enable_guest_swap is enabled, insert a raw file to the guest as the
swap device if the swappiness of a container (set by annotation
"io.katacontainers.container.resource.swappiness") is bigger than 0.
The size of the swap device should be
swap_in_bytes (set by annotation
"io.katacontainers.container.resource.swap_in_bytes") - memory_limit_in_bytes.
If swap_in_bytes is not set, the size should be memory_limit_in_bytes.
If swap_in_bytes and memory_limit_in_bytes is not set, the size should be
default_memory.

If specified, sandbox_bind_mounts identifies host paths to be
mounted (ro) into the sandboxes shared path. This is only valid
if filesystem sharing is utilized.
The provided path(s) will be bindmounted (ro) into the shared fs directory on
the host, and thus mapped into the guest. If defaults are utilized,
these mounts should be available in the guest at
`/var/run/kata-containers/shared/containers/sandbox-mounts`
These will not be exposed to the container workloads, and are only
added for potential guest-services to consume (example: expose certs
into the guest that are available on the host).

Add a field "enable_annotations" to the runtime configuration that can
be used to whitelist annotations using a list of regular expressions,
which are used to match any part of the base annotation name, i.e. the
part after "io.katacontainers.config.hypervisor."
For example, the following configuraiton will match "virtio_fs_daemon",
"initrd" and "jailer_path", but not "path" nor "firmware":
enable_annotations = [ "virtio.*", "initrd", "_path" ]
The default is an empty list of enabled annotations, which disables
annotations entirely.
If an anontation is rejected, the message is something like:
annotation io.katacontainers.config.hypervisor.virtio_fs_daemon is not enabled

Support the `sgx.intel.com/epc` annotation that is defined by the intel
k8s plugin. This annotation enables SGX. Hardware-based isolation and
memory encryption.
For example, use `sgx.intel.com/epc = "64Mi"` to create a container
with 1 EPC section with pre-allocated memory.
At the time of writing this patch, SGX patches have not landed on the

To control whether guest can enable/disable some CPU features. E.g. pmu=off,
