Gábor Gyimesi updated MINIFICPP-2377:
-------------------------------------
    Description: 
Controller services are parsed from the root level in the yaml configuration 
and from the rootProcessGroup in the json configuration. In both cases these 
controller services have global scope in the flow configuration, and can be 
used by any processor in any process group. In NiFi there are Management 
Controller Services and process group level controller services. The Management 
Controller Services are global and can be used by any processors and do not 
support parameters, while the process group controller services can only be 
used by the processors in that process group, but they also support using 
parameters from the process group's parameter context.

We should find a backward compatible way to support both global and process 
group level controller services in both yml and json flow configurations.
