Since nifi-azure-processors depends on nifi-standard-processors, this
dependency should be changed to nifi-standard-nar, which specifies a dependency
on nifi-standard-services-api-nar itself. This will enable nifi-azure-nar's
classloader to have the classes that are depended upon (in
nifi-standard-processors) by nifi-azure-processors, which in turn allows
nifi-azure-processors to specify nifi-standard-processors as a provided
dependency, which fixes the standard processors being loaded twice.
