Winner Submission of the challenge Topcoder TaaS API - Data Scripts

[shailesh-02]

Created scripts for importing and indexing data to ES

Winner submission from the challenge https://www.topcoder.com/challenges/8a2bed05-e102-47db-945c-f165438fb68e?tab=details with final fixes:

1. Check https://prnt.sc/xt0tz0. Such warning should be removed.
2. indexing uses different IDs than DB and not UUID. This has the side effect of the API not able to load related documents like job#candidates and if re-indexing with ID later, it will add duplicate records.
3. At the moment time is always shown in milliseconds for average time, time spend and time left. Instead of always showing milliseconds, let's show time so it's easier to read for humans like:
   "1 year 3 months 2 weeks 7 days 16 hours 58 minutes 17 seconds 856 milliseconds"
4. Merge with the latest dev branch and resolve conflicts
