Improve article recommendation pipeline

The article recommendation pipeline consists of many parts. The project aims to improve article recommendation pipeline by solving the various issues in the article-recommender projects.

The few issues which are going to be worked upon are:

• Remove duplicate Wikidata items from article recommendations
• Recommendation API translation endpoint stopped working
• Article recommendation API: replace WDQS with MW API
• 'morelike' recommendation API: Bulk import data to MySQL in chunks
