If I understand correctly the work that is being done in Composable
HA, Redis will be able to be deployed with Pacemaker on a dedicated
node:

I'm not sure if we can deploy it with systemd only, in a HA manner but
Michele could eventually confirm.

Regarding the timeline to do it in Ocata, I'm really not sure that's
doable, it depends on the Composable HA progress I guess.
