The next obvious step in porting to cfg is to define all options using
cfg schemas directly rather than using the flags.DEFINE_* helpers.
This is a large change, but it is almost entirely pure refactoring and
does not result in any functional changes.
The only change to note is that the default values for glance_host,
glance_api_servers and default_publisher_id options are now using opt
value interpolation i.e.
-glance_host=_get_my_ip()
+glance_host='$my_ip'
-glance_api_servers=['%s:%d' % (FLAGS.glance_host, FLAGS.glance_port)]
+glance_api_servers=['$glance_host:$glance_port']
-default_publisher_id=FLAGS.host
+default_publisher_id='$host'
Also note that the lower_bound check on the {report,periodic}_interval
options are no more, but this has been true since cfg was first added.
