Add RecordSinkServiceLookup

The RecordSinkService controller service interface was added in NiFi 1.10 (via NIFI-6780) to decouple the destination for records in a FlowFile from the format of those records. Since then there have been various implementations (NIFI-6799, NIFI-6819). Other controller services have been augmented with a "lookup" pattern where the actual CS can be swapped out during the flow based on an attribute/variable (such as DBCPConnectionPoolLookup).

RecordSinkService could be improved to have such a lookup as well, especially with the advent of the PutRecord processor (NIFI-6947). This would allow some flow files to be routed to Kafka while others are sent Site-to-Site for example, all with a single configured controller service.
