URL Shortener Microservice

User Stories:

1. I can POST a URL to [project_url]/api/shorturl and I will receive a shortened URL in the JSON response.
   Example: {"original_url":"https://www.freecodecamp.org","short_url":"jf71vgvg3n"}
2. If I pass an invalid URL that doesn't follow the http(s)://(www.)example.com(/more/routes) format, the JSON response will contain an error like {"error":"invalid URL"}
3. When I visit the shortened URL, it will redirect me to my original URL.
