Authorize client for ‘resouce owner’ using client credentials and refresh token.

For authorization, authorize function requires a map contains ‘client_id’ and ‘client_secret’ and ‘refresh_token’. With valid credentials; it automatically creates access_token and refresh_token(if enabled via config) then it returns Gandalf.Model.Token struct, otherwise {:error, Map, :http_status_code}.

Gandalf.GrantType.RefreshToken.authorize(%{
  "client_id" => "52024ca6-cf1d-4a9d-bfb6-9bc5023ad56e",
  "client_secret" => "Wi7Y_Q5LU4iIwJArgqXq2Q",
  "refresh_token" => "XJaVz3lCFC9IfifBriA-dw",
  "scope" => "read"
