URL shortener

The implemented service provides an API for creating shortened links in the following format:

• The link is unique and only one shortened link refers to one original URL.
• Link 10 characters long
• The link consists of lowercase and uppercase Latin characters, numbers and the _ symbol (underscore)

The service is written in Go and accepts the following http requests:

1. Method POST, which saves the original URL in the database and returns a shortened one
2. Method GET that takes a shortened URL and returns the original URL
