Make GET request navigable

[rafaelcamargo]

At the moment, get requests respond with all results found. So, requests are taking very long for big amounts of data.
Make pagination enabled by default for any get requests. Suggestion:

1. List 30 results per page by default
2. Allow an optional query param called page.
3. Allow an optional query param called pageSize to change the default value for the number of results per page.
4. Include a link attribute in response header containing navigation details:
   • e.g.: Link: <https://api.github.com/users?page=2>; rel="next", <https://api.github.com/users?page=50>; rel="last"
