Add status code to RequestError

[TitouanS31]

I would like to add a way to retrieve the status code from RequestError to handle these exceptions differently, depending on their status. As a concrete example, I want to silently catch some 504 errors, since they do not seem to be a real problem (cf. #23).

You should be able to get the error information from the exception that is raised:

try:
    # make call
except RequestError as foo:
    status_code = foo.req.status_code

Thank you, I did not see the req attribute.
