Support systemd-cgroup
When configuring CRI-O to use cgroup_manager = "systemd" these errors appeared:
flag provided but not defined: -systemd-cgroup
Seems like currently we do not support this configuration.

Agreed. It appears runc supports this (global non-OCI-required) option [*], but cc-runtime currently doesn't:
$ sudo docker-runc --help|grep systemd
--systemd-cgroup enable systemd cgroup support, expects cgroupsPath to be of form "slice:prefix:name" for e.g. "system.slice:runc:434234"
$ sudo docker-runc --version
runc version 1.0.0-rc2
commit: 9c2d8d184e5da67c95d601382adf14862e4f2228
spec: 1.0.0-rc2-dev

Technically it's not an OCI issue, it's a runc compatibility issue, so tagging with that too.
