Do not log 14+ INFO lines on a broken pipe error (eventlet)

Under eventlet if the client disconnects while Keystone is trying
to transmit data, approximately 14 lines of traceback are logged.

This could result in massive logs if done repeatedly; worst case
scenario could include a denial of service due to disk space being
exhausted.
