Updated standalone-ha.xml to fix 'socket-binding' error

I was getting an error in boot.log something about 'socket-binding' (I lost the log). I diffed the ha xml from the latest build and this one. This change was the first thing I tried, and it fixed the problem.

I don't know enough about the settings to know for sure what I did. I also don't know how many people are using chef to deploy, but it would be nice if breaking changes could get folded into this repo.

Thanks!
