Sync importutils from openstack-common.
commit 8c74b37f5bdf1141b8c3724c8df460e6562d1985
Author: Russell Bryant <rbryant@redhat.com>
Date: Tue Jun 19 17:08:35 2012 -0400
Improve exception from importutils.import_class().
The ImportError raised by import_class() attempted to tell you what the
original error was by just doing str() on the original exception.
Sometimes that's helpful, but sometimes a full traceback is needed.
This patch includes a traceback for debugging purposes.
