> Streaming data will grow very fast and consume huge storage. since queries are focus
on recent data only in most of cases, support data retention in streaming data model is a
critical feature to control storage size and even query performance.
> 1. Add one config setting option in streaming data model
> 2. User could define how long to keep data, for example, 7 days, 30 days. 
> 3. This is management option which could be updated on the fly
> 4. Default retention option should be controlled by kylin.properteis file.
