* Move liberty -> approved * Move completed liberty specs to liberty-implemented * Move kilo -> kilo-implemented * Move juno -> juno-implemented * Move kilo-archive -> backlog (moving these to approved causes test failures because the template changed since kilo) * Reword the header for the index page * Update unit tests to look at the new "approved" folder ** NOTE ** This patch does not create placeholders in the previous locations for each spec. This will be done in the following patch so that the history is preserved. Both patches must be landed together so that web links are not broken for long.

Driver Internal Info
https://blueprints.launchpad.net/ironic/+spec/driver-internal-info
Problem description
Driver should have its own infos which cannot manipulated by user/admin. These infos are not input from admin like driver_info and they may vary during the deployment process. They can only be used by driver itself.
One example is ipmitool. Not all IPMI firmware support set boot device persistent, so we need to save this locally.
Proposed change
- Add a new internal attribute driver_internal_info in nodes table, which cannot modify by Admin/user by calling node.update API
- Modify node.update to clear driver_internal_info when update driver via node.update API.
Alternatives
Saving these infos in a new table named driver_interal_info.
Data model impact
Add a new internal attribute driver_internal_info in node table. This field is a json dict.
REST API impact
The driver_internal_info field should be added to the node details API.
