Description

The documentation for both PrometheusReportingTask [1] (reporting task) and PrometheusRecordSink [2] (controller service) state that NiFi Variable Registry can be used to define the port. However, configuring NiFi EL in the port property results in:

java.lang.NumberFormatException: For input string: "${<variable registry property name>}"

Support variable registry here would allow user to set a unique port on each host in a NiFi cluster.
