Correct 4xx/5xx response management in SessionClient

Currently SessionClient raises an exception when status code >= 400
unlike HTTPClient. neutronclient.v2_0.client expects HTTPClient
behavior.

This change disables exception raise when status code >= 400 in
SessionClient (more precisely in keystoneclient.session).
