[GoEx] Added additional support for GoEx DBs and APIs.

[YLu-1258]

GoEx Db

• Created additional DBManagers for PostgreSQL and MongoDB databases.
• Implementation for MongoDB is limited as it is a document-based db, rather than SQL.
  • Included sample driver code to test MongoDB operations.

GoEx APIs

• Utilized the Spotipy module to create basic APIs to spotify (album and playlist details)

Thank you for the PR @YLu-1258 ! Similar to the previous comment, please also do update the readme - on how we can test these out, so a) we can test it out locally, and b) it will be useful to users who want to use this.

Hello Mr. Patel,

Sorry for the very late response! Alex and I have been very busy with midterms and we have just finished. I have updated the read me with steps on how to test the functions for the Spotify APIs implemented.

Thank you for your patience and understanding,
