    Fix an issue with libvirt pods not starting

    The cgroup folder has been changed by commit:

    As a result the new hugepage folder was being created at:
    However the helm-chart default location was still looking at:

    The k8s-infra label for the cgroup folder has now been added
    to the armada manifest, and libvirt pods are able to launch.

As per Al Bailey, this issue was introduced by two recent commits:

The first commit had a bug which became a fatal error once the second commit went in to upversion helm. Both commits were merged at the same time. That's why the issue was not seen in individual designer testing.
