[infinispan-dev] All demos should be readily discoverable by RHQ

[Galder Zamarreño]

Just had a chat with John and Ian and it could be doable via process scanning cos they do find JMX servers even if port is missing. However, it'd require some subclassing. I don't think this is top priority right now although a nice to have at some point.

I'll make a note for a future improvement, but right now I'm more worried about making sure it all looks good from an RHQ management perspective.

I think I've fixed all issues now and will focus on making it easy to run two GUi demos with diff JMX port. To be honest, we don't care what the ports are as long as one is used, so some kind of random port selection would be ideal although not sure how easy to achieve since you'd have to check that something is not running in that port. 

So, Sanne's suggestion of making it easier to run with a diff JMX port could be handy. 

Or alternatively have RHQ monitoring params commented in the script so that people can uncomment them with little pain. Similar to remote debugging ones. I'll probably go with this option.
