Make FLAGS a ConfigOpts instance and fix up all the places where we
expected FlagValues behaviour.

Move it here so that it can be kept in sync with openstack-common using
the new update.py script for code in openstack-common's incubation area.
See here for more details:
http://wiki.openstack.org/CommonLibrary#Incubation
Note: this commit just moves the existing code in Nova with no other
changes. A subsequent commit will sync it with latest openstack-common
so that it is easier see the new changes.

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.
