API Basejump: URL Shortener

User stories:

• I can pass a URL as a parameter and I will receive a shortened URL in the JSON response.
• When I visit that shortened URL, it will redirect me to my original link.

Example creation usage:

https://im-urlshortener-ms.glitch.me/new/https://www.google.com

https://im-urlshortener-ms.glitch.me/new/invalid?allow=true
