When a container is updated, those modifications are stored, to
avoid race conditions with other operations, a RW lock should be used.

k8s provides a configuration for sharing PID namespace
among containers. In case of crio and cri plugin, an infra
container is started first. All following containers are
supposed to share the pid namespace of this container.
In case a non-empty pid namespace path is provided for a container,
we check for the above condition while creating a container
and pass this out to the kata agent in the CreatContainer
request as SandboxPidNs flag. We clear out the PID namespaces
in the configuration passed to the kata agent.

As the comment in the code showed, now that
https://github.com/kata-containers/osbuilder/issues/25 is fixed, it is
no longer necessary to specify an image size to the image builder as it
will auto-calculate it.

Don't default to a hard-coded Intel architecture - default to the host
architecture.
This requires the `coreutils` package to be installed both inside each
docker image (for `USE_DOCKER=true`) and in the host environments.
Added missing SPDX headers to `Dockerfile` templates to pacify the CI checks.
