Looks good, merging
> Controller Services are not automatically enabled/disabled when joining

> Key: NIFI-5012
> URL: https://issues.apache.org/jira/browse/NIFI-5012
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
>
> If a node is disconnected from the cluster, a user is able to navigate to the
> disconnected node and stop processors/controller services. Upon re-joining
> the cluster, the node should inherit the cluster's run state for all
> components. This works for processors but appears not to enable controller
> services as expected. To duplicate, we can create a simple flow, as attached
> in a template.
> Disconnect one node from the cluster. Navigate to the disconnected node,
> disable the CSVReader controller service. Now re-join back to the cluster.
> When the node rejoins, instead of the Controller Service being enabled, the
> service is still disabled on this node, and the ConvertRecord processor is
> invalid as a result. If you navigate to the Controller Services for the
> Process Group, though, it shows that the service is enabled. As a result, if
> the ConvertRecord processor is already running when re-joining, it will show
> as running but still be invalid on one node.
