> Create a generic way to compute aggregation on top of chukwaRecords based on a config file
> Should be able:
> - work on several Chukwa streams 
> - To aggregate by time period
> - Group by values for specific keys
> - Provide a redefine list of functions (AVG,MIN,MAX,Counter->Rate conversion...)
> - work with new functions
