Mark McLoughlin 82049af90e Refactor away the flags.DEFINE_* helpers
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.
