Description

When a user chooses to enable a Controller Service and its referencing components, there exists a situation where we can sometimes see the referencing Controller Service fail to enable. This is particularly problematic in a clustered environment, as it can result in nodes being disconnected from the cluster because the service didn't enable.

To replicate, create a JSONRecordSetWriter service and an AvroSchemaRegistry service. Configure the record writer to depend on the schema registry (and all other necessary configuration to make the services valid). Now, enable AvroSchemaRegistry and all referencing components. The JSONRecordSetWriter will sometimes fail to enable because it is not yet valid.
