dockerfile for rhq 

dockerfile for rhq (4.10.0 release version) 
What for installing requires server? What kind of data it seeds there? This should be the same for all containers prepared this way.

What I'm thinking is more this line: create a separate PostgreSQL image that is preconfigured to run with RHQ and skip as many preparations as we can because it simply makes the boot slower. Customizing the hostname is an easy step after boot and would not take as much time as preparing everything once again.

Another thing is: what if we have a database that was already used and we start a new container that uses this DB? Would be the data reused or it'll be initialized one more time? (I don't know the `rhqctl install` internals).
