Issue XD-2559: Add Redis based Aggregate Field Value Counters
As a user, I'd like to have a Redis based _aggregation_ over field-value counters so that I can continuously write the aggregation in Redis as we ingest more data. *Scope:* * Port specs from [previous implementation|https://github.com/spring-projects/spring-xd/wiki/OLD---Aggregate-Field-Value-Counters]. * Identify gaps * Update reference documentation
