Title: Implement OAuth 2.0 refresh access token

Some OAuth providers ask to extend the access token expiration date, in
order to continue using it.
Microsoft Live do that, and it will be soon mandatory for Facebook
because they will deprecate the 'offline_access' permission.

To refresh an access token, you need to access the accessTokenEndPoint
with other parameters like a specific 'grant_type' parameter.
