Liberty release cruft updates

This patch updates the ops guide to remove some ancient cruft
and update "current" links to the Liberty release URLs. Includes:
* remove note on period tasks fixed in Grizzly
* IPv6 support now works in neutron
* global clustering is no longer a new feature
* glance quotas is no longer a new feature
* object quotas is no longer a new feature

-      <para>Before the Grizzly release, the frequency of periodic tasks was

-      took 30 minutes to run and the frequency was set to hourly, then the

-      the task does. So, our 30 minute periodic task will run every hour, with
