feat(oauth): new statements for authorization_details and request_uri

[RebeccaSelvaggini]

The first new statement looks like
Given I send request 'request' and send server_data 'server' and verify request parameters
given the parameters of an /authorize request, it checks the validity of the given request_uri and client_id in request.

The second statement looks like
Given I send request_uri 'request_uri' and send data 'data' and send server_data 'server' and add data to authorization_details and output into 'auth_details'
given a request_uri and a string dictionary data, it updates the authorization_details linked to the request_uri adding a new field claims that contains the dictionary data.

Seems good, the only thing that maybe I would change is the authorization_details by removing the underscore. We use it before since the parser can take only one word as parameter key, but in the statement identifier we do not have this problem and without the underscore it can be more readble and easier to remember (as also all the other statement indentifiers do not have underscore in this plugin)

I just add that some documentation will be beneficial for everyone ;p and a little bit more testing
