A guest or an authenticated user can list questions

[josepostiga]

Scenario

Given I'm a guest or an authenticated user of any type
When I send a GET request to /discussions/questions
I expect to receive a list of paginated, non-deleted, questions resources (15 per page)

Given I'm a guest or an authenticated user of any type
When I send a GET request to /discussions/questions with any searchable properties
I expect to receive a list of paginated, non-deleted, questions resources that match the query param (15 per page)

Given I'm a guest user
When I send more than 30 GET requests to /discussions/questions within a single minute
I expect to receive a 429 Too Many Requests status code until the next minute

Searchable properties

• author_id: mapped to an author query param (?author={id}).
• title: mapped to a title query param (?title={search-text}).
• created_at: mapped to a created[] period type query param (?created[from]={start-period}&created[to]={end-period}).
• resolved_at: mapped to a resolved query param (?resolved=true).

Additional requirements

The list should be ordered from the most recent resources to the eldest.

This builds on the features of #25, which introduces the storage of questions resources.
