Add missing systemctl step for running cri-o

mattjmcnaughton · mattjmcnaughton · commit ba823d1dd1fb · 2019-12-03T08:31:35.000-05:00
After installing `cri-o`, we must run `systemctl daemon-reload` before
trying to run `systemctl start crio`. Otherwise, `systemd` doesn't know
about the crio configuration.

Similar instructions already exist for installing docker - this diff
adds these instructions for crio.
