Description

I want to be able to use `PROFILER_APPLY` with live messages from a Metron cluster. For example, I would like to be able to grab 10 messages from Kafka and then apply them to my debugger. This would be tremendously helpful for iterating between the debugger and a live cluster when troubleshooting.

p := PROFILER_INIT(conf)
msgs := KAFKA_GET("indexing", 10)
PROFILER_APPLY(msgs, p)
PROFILER_FLUSH(p)

The `PROFILER_APPLY` function does not currently accept a list of messages. It accepts a String that is a JSON list, but not a Stellar list. For `PROFILER_APPLY` to play happy with `KAFKA_GET` (and other potential uses) it needs to accept a List.
