Update cfg from openstack-common

Use openstack-common's update.py script to pull in some recent changes:

 * Add the Mapping interface to cfg.ConfigOpts
 * Add support to cfg for disabling interspersed args

Make use of both of these in nova/flags.py.

Add some dire warnings to HACKING about directly modifying the copy of
openstack-common code. I'm confident they won't be ignored :-)
