Move  requests to codeclimate api into extra class

@leoniddinershtein this is standart way for `httparty` to setup API base url. 
Where you recommedn to move constant?

This code bellow looks a little bit too verbose.

````ruby
class ApiRequester
    include HTTParty

   CODECLIMATE_BASE_URL = 'https://codeclimate.com/api/repos'

    base_uri CODECLIMATE_BASE_URL
end
```
