When we get a pod with DNS settings, we need to build
a resolv.conf file and mount it in all pod containers.
In order to do that, we have to track the built resolv.conf
file and store/load it.

We have moved selinux support out of opencontainers/runc into its
own package. This patch moves to using the new selinux go bindings.

We need to support a 2x2 matrix of use cases with both
kubelet giving us (command, args) slices and the OCI
image config file giving us (ENTRYPOINT, CMD) slices.
Here we always prioritize the kubelet information over
the OCI image one, and use the latter when the former
is incomplete.
Not that this routine will be slightly simpler when
issue #395 is fixed.

If I create a sandbox pod and then restart the ocid service, the
pod ends up in a stopped state without an exit file. Whether this is
a bug in ocid or not we should handle this case where a container exits
so that we can clean up the container.
This change just defaults to exit code to -1 if the container is not
running and does not have an exit file.

When starting pods or containers, we create the mount points
first. It seems natural to do something symetrical when stopping
pods or containers, i.e. removing the mount point at last.
Also, the current logic may not work with VM based containers as the
hypervisor may hold a reference on the mount point while we're trying to
remove them.

The way we build the OCI Process Args slice is incorrect.
With the current implementation we may for example end up building this
slice with only the entry point arguments, if the kubelet passed
information is missing the Command slice.
We also will end up building the Args slice with the Image config
process arguments, without the defined entry point, if kubelet does not
tell us anything about the container process command to be run.
This patch fixes that by favoring the kubelet ContainerConfig
information. If that is missing, we try to complete it with the
container image information. We always use ContainerConfig.Command[] or
ImageConfig.EntryPoint[] as the first OCI Process Args slice entries.

This also updates the readme to no longer contain CNI configuration
information (which had incorrect steps), and rather just points to the
example configs.

The pause container is creating an AVC since the /dev/null device
is not labeled correctly. Looks like we are only setting the label of
the process not the label of the content inside of the container.
This change will label content in the pause container correctly and
eliminate the AVC.

The sandbox privileged flag is set to true only if either the
pod configuration privileged flag is set to true or when any
of the pod namespaces are the host ones.
A container inherit its privileged flag from its sandbox, and
will be run by the privileged runtime only if it's set to true.
In other words, the privileged runtime (when defined) will be
when one of the below conditions is true:
- The sandbox will be asked to run at least one privileged container.
- The sandbox requires access to either the host IPC or networking
namespaces.

We add a privileged flag to the container and sandbox structures
and can now select the appropriate runtime path for any container
operations depending on that flag.
Here again, the default runtime will be used for non privileged
containers and for privileged ones in case there are no privileged
runtime defined.

Not all runtimes are able to handle some of the kubelet
security context options, in particular the ones granting
host privileges to containers.
By adding a host privileged runtime path configuration, we
allow ocid to use a different runtime for host privileged
operations like e.g. host namespaces access.
