48a297ed7b container: Propagate the pod sandbox resolv.conf mount point
When a pod sandbox comes with DNS settings, the resulting resolv.conf
file needs to be bind mounted in all pod containers under

72129ee3fb sandbox: Track and store the pod resolv.conf path
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.

6f81ec8c67 Default all container storage to /var/lib/containers/storage
containers/storage is defaulting to /var/lib/containers/storage
for image and containers storage.  It is also defaulting to
/var/run/containers/storage for all runtime.  The defaults
for CRI-O should match so that lots of other tools that use
containers/storage can share the same storage.

21afa1a975 server: Fix the OCI process arguments build routine
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.

d679da0645 If the container exit file is missing default exit code to -1
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.

c3cb6a133f server: Remove the mount points after stopping the containers
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.

4ac92d73e4 container: Fix the OCI Process Args string build
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.

ff950a8e37 Set SELinux mount label for pod sandbox
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.

2ec696be41 server: Set sandbox and container privileged flags
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.

2fc4d0cac1 config: Add host privileged runtime configuration
Not all runtimes are able to handle some of the kubelet

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.
