[Pacemaker] Notes on pacemaker installation on OmniOS

[Grüninger, Andreas (LGL Extern)]

I am really sorry but I forgot the reason. It is now 2 years ago when I had problems with starting pacemaker as root.
When I remember well pacemaker got always access denied when connection to corosync.
With a non-root account it worked flawlessly.

The pull request from branch upstream3 can be closed.
There is a new pull request from branch upstream4 with the changes against the current master.

I'm curious... what was the old reason?

Definitely to isolate them with an appropriate #define (preferably by feature availability rather than OS)

Is there anything left in them that needs to go in?
If so, can you indicate which parts are needed in those pull requests please?
The rest we can close - I didn't want to close them in case there was something I had missed.
