Description

The fairly new AzureStorageCredentialsControllerServiceLookup and the DBCPConnectionPoolLookup have 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 services of a given type 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.
