Limitations

* For some reason Amazon doens't return consistent data for scrapping. Right now even if the scrapper doesn't 
get the required data it pushes the url to the db. If after it gets the data after retries, it updates the 
respective data in the db. 

TODO

* Use ENV variables
* Appropriate naming for variables, api, etc
* Use a response for the web-scrapper-api
* Add better comments
