I would like to see a slightly broader goal: replace parts of the OSE3
roadshow lab with nuleculized content.

If you take a look at lab 6 and 7 of the OSE3 roadshow, it will deploy
 some EAP and Mongodb. Both could be reused to show a good Nulecule
 Uber Example:

1. persistent storage - for mongodb nodes
2. deploy (via atomicapp) and scale (via oc) a mongodb replica set
3. deploy a dependent component (EAP)
