RDB Loader, Storage Loader, EmrEtlRunner

@AllenWeieiei, RDB Loader is a new name for Storage Loader. You need to set up batch job orchestrated by EmrEtlRunner. The RDB Loader will be part of this data processing (specify it in EmrEtlRunner configuration file). To set up the job for this task you can start your journey from https://github.com/snowplow/snowplow/wiki/1-Installing-EmrEtlRunner. Do bear in mind 2 way of processing the data depending on if your load streamed data from Raw stream of from Enriched stream. The latter will enable Stream Enrich mode for EmrEtlRunner. The diagram depicting both modes is here.
