Make cluster-stack-version show up in the CLI

[Vincent-lau]

This makes cluster-stack-version show up as a field of the cluster object in cli

We also have

[root@lcy2-dt110 ~]# xe host-param-get param-name=software-version uuid=c1517689-49cd-4088-9f20-149678beb526

Ok, what does this have to do with my PR? Or are you just pointing out something interesting?

If we are looking for a way to report versions, extending xe host-param-get param-name=software-version would be a good way. Why do we need different methods?

[Vincent-lau]

Ah, that's because it is not just for reporting versions, it also controls which version of the cluster-stack (corosync) will be started, and used internally in all sorts of places. I think extending the software-version would work just fine as well, but that would require parsing that string in order to find out the cluster-stack-version?

That said, using software-version would probably work just as well, and makes them all in one place, but it is probably too late to change this design....

We could create a ticket to report the version there in addition? Maybe for @last-genius
