In order to support DPDK workloads, we need to change the way VFIO devices
will be handled in Kata containers. However, the current method, although
it is not remotely OCI compliant has real uses. Therefore, introduce a new
runtime configuration field "vfio_mode" to control how VFIO devices will be
presented to the container.
We also add a new sandbox annotation -
io.katacontainers.config.runtime.vfio_mode - to override this on a
per-sandbox basis.
For now, the only allowed value is "guest-kernel" which refers to the
current behaviour where VFIO devices added to the container will be bound
to whatever driver in the VM kernel claims them.

The physical current vcpu number should not be used directly as the

The current kernel version parse lib can't process suffix '+', as the
modified kernel version will add '+' as suffix, thus panic will occur.
For example, if the current kernel version is "5.14.0-rc4+", test
TestHostNetworkingRequested will panic:
--- FAIL: TestHostNetworkingRequested (0.00s)
panic: &{DistroName:ubuntu DistroVersion:18.04
KernelVersion:5.11.0-rc3+ Issue: Passed:[] Failed:[] Debug:true
ActualEUID:0}: failed to check test constraints: error: Build meta data
is empty
Here, remove the suffix '+' in kernel version fix helper.

This PR includes these optimize changes:
- Remove the dependency on the container engine.
The old code uses runc to generate config.json and
Docker to export rootfs, that will be heavy and need
additional dependency.
Using a fixed config for busybox image can avoid
the heavy processing above.
- Moved duplicate code to pkg/katatestutils package

When the container engine is different than containerd or CRI-O we
lack proper detection of kata workloads and consider all the pods as
kata ones.
Instead of querying the container engine for the lower level runtime
used in each pod, check if a directory matching the pod exists in
the virtualcontainers sandboxes storage path.
This provides a container engine independent way to check for kata pods.

Signed-off-by: Francesco Giudici <fgiudici@redhat.com>
The storage path we use to collect the sandbox files is defined in the
virtcontainers/persist/fs package.
We create the runtime socket in that storage path, by hardcoding the
full path in the SocketAddress() function in the runtime package.
This commit splits the hardcoded path by the socket address path so that
the runtime package will be able to provide the storage path to all the
components that may need it.

In order to retrieve the list of sandboxes, we poll the container engine
every 15 seconds via the CRI. Once we have the list we have to inspect
each pod to find out the kata ones.
This commit extend the sandbox cache to keep track of all the pods,
marking the kata ones, so that during the next polling only the new
sandboxes should be inspected to figure out which ones are using the
kata runtime.

We keep the container engine info in the sandbox cache map, as the value
associated to the pod id (the key). Since we used that in
getMonitorAddress() only (which is gone) we can avoid storing that
information. Let's drop it.
Keep the map structure and the [put,delete]IfExists functions as we may
want to move to an event based cache update process sooner or later, and
we will need those.

kata-monitor uses containerd client to retrieve information from the
container engine. This makes kata-monitor work with the containerd
container engine only.
Bin Liu (bin <bin@hyper.sh>) worked on a kata-monitor version able
to talk to any container engine leveraging the standard CRI[1].
Here, the original work of Bin Lui has been adapted on the current
kata-monitor to make it container engine independent.

"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
