Extension:OpenStackManager

Simple development spec
that this is mostly written from a Wikimedia Foundation perspective for now.

Nova manager

 * Software requirements
 * APIs:
 * AWS PHP API
 * MediaWiki extensions:
 * LDAP authentication
 * Semantic MediaWiki
 * Semantic Forms
 * Semantic Result Formats
 * External Data
 * Parser Functions
 * Dynamic Sidebar
 * Authentication:
 * LDAP using OpenDJ
 * Possibly using also using OpenAM?
 * Console access:

 * ajaxterm
 * DNS:

 * Each project is a namespace. Only users in the ldap project group are given access
 * Make new right for vm management
 * Restrict renames to project members
 * Admin users can edit/manage all
 * How to handle editing of VM documentation? Only allow project members to do so? Allow writes to pages, but restrict edit access to manage interface to project members? Allow talk page modification only? Let the wiki sysadmin make these decisions and allow all?
 * How to create/delete namespaces dynamically? How to assign numbers to the namespaces, and have them be unique?
 * VM management
 * Special page for creating VMs
 * Create a documentation page on creation
 * Set userData['instance-name'] to fulltitle on instance creation, so that the name will be unique, and we can filter later instead of relying on instanceId

 * Special page for resizing VMs
 * Special page for managing snapshots
 * Enable snapshot schedule

Swift manager
TODO after Nova manager is complete.

Installation
Download the trunk snapshot and untar into the extensions directory. Download the AWS PHP library, and add it as aws-sdk under the OpenStackManager directory. Add the following to LocalSettings.php:

there is currently a bug in the AWS PHP SDK that causes requests to OpenStack to fail; ensure you apply the patch described here.

Roadmap
See spec for now.
