Please rebase to latest master so we can get better testing/contrib-check.
Also, please convert those unit tests to integration tests. They are very
timing sensitive and highly reflective of the types of things we just coverted
to IT in many cases to get the builds stable again.

> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.1.0
> Reporter: Arpit Gupta
> Assignee: Mark Payne
> Fix For: 1.5.0
>
>
> Here is the scenario
> 1. Create a flow and start a processor
> 2. Disconnect a node
> 3. On the disconnected node stop the above processor
> 4. Connect the above node to the cluster
> 5. Wait 30s.
> 6. Check if the processor started on the node that was connected in #4.
> Very intermittently we see that the processor does not get into running state.
> When we query the processor status on the node we get the following bulletin
> {code}
