                 Key: NIFI-6729
                 URL: https://issues.apache.org/jira/browse/NIFI-6729
             Project: Apache NiFi
          Issue Type: Improvement

The new  fairly new {{AzureStorageCredentialsControllerServiceLookup}} and the {{DBCPConnectionPoolLookup}} has a lot of common logic and points to a general concept that could be captured with an abstract implementation: 

A utility service that looks up a certain type of service from a predefined list.
These services are mapped to predefined string keys.
Which service is to be used is determined based on a flowfile attribute that holds the corresponding predefined key.
