Add support for cgroup driver systemd. systemd cgroup is not applied in the VM since in some cases like initrd images there is no systemd running and nobody can update a systemd cgroup using systemctl. fixes kata-containers#596 Signed-off-by: Julio Montes <julio.montes@intel.com>

I wonder if we can do the conversion in the cli package instead?

I thought the same, the problem is that systemd cgroup should be applied in the host (if systemd is the init process and where docker is running), so I prefer to modify the grpcSpec before sending it to the agent and don't modify the original ociSpec to let virtcontainer apply it in the host

I'm adding host cgroup support currently: #734 Wondering if this should also apply to host cgroup? When user/docker specify systemd cgroup, which layer do they want to apply? Host Cgroup or Guest Cgroup? |
Systemd cgroup should be applied in the host, not in the guest

@devimc Oh, I mis-read your description, this is good to me. I'll take this into consideration while doing host cgroup support, but this depends on the flag provided by your PR. LGTM |

Add support for cgroup driver systemd.
systemd cgroup is not applied in the VM since in some cases like initrd images
there is no systemd running and nobody can update a systemd cgroup using
systemctl.
