Description

I'm thinking about the following changes:

• use in-memory cluster state store in all service integration tests
• it should be possible to run integration tests in parallel (easy with no state and port conflicts)
• each service integration test should be executed on multiple OSes: Ubuntu / Debian and Centos. We should be able to set a flag to get this behavior.
• refactor and write missing tests for ClusterStateStore (as discussed in WHIRR-288)

I'm going to create a subtask for each fix.

What do you think? What else should we do to improve the testing process?
