For this challenge, we'd like to add a new job similar as srms and mmatches, which will populate all rounds related data including srms and mmatches.

General Requirements

- Create a es mapping file for round (name it round.json), similar as https://github.com/topcoder-platform/tc-elasticsearch-feeder-service/blob/dev/es-mappings/srms.json
-- isRatedForSRM field should be renamed to isRated to be general
-- Add fields for roundTypeId and roundTypeName
-- Add fields for contestId

--* problem_id - component.problem_id

-- Update src/main/java/com/appirio/service/challengefeeder/api/DataScienceData.java to support the new fields.
- Create the DAO class and related sqls to support getting these data.
