Run on terminal

Go to localhost:8080/dogs or localhost:8080/cats

The list of redirection should be maintained in a command line tool, what can:

• Manipulate YAML config file. Where the redirection list peristently stored.
• Implement append to the list: ./url-shortener configure -a dogs -u www.dogs.com
• Implement remove from the list: ./url-shortener -d dogs
• List redirections: ./url-shortener -l
• Run HTTP server on a given port: ./url-shortener run -p 8080
• Prints usage info: ./url-shortener -h

• Track number of times each redirection is used. When the user uses urlshorten -l, the user should see redirections ranked by how many times they have been used.
• Provide a default shortening, if no example is given. For example, if dogs is not given, generate a random alphanumeric string of length 8.
• Build a Handler that doesn't read from a map but instead reads from a database. Whether you use BoltDB, SQL, or something else is entirely up to you.
