All of the prerequisites for supporting multiple VM providers should be in place. This has been tested with rackspace legacy, rackspace nova, and hpcloud. The scripts now use novaclient instead of libcloud. The old v1_0 code that was removed from novaclient is added here for as long as we continue to use rackspace legacy. It's slightly modified to handle some operational considerations (such as cache-busting), and to integrate with the current version of novaclient. We can remove it when it's no longer needed. Machines are now generated from snapshot images created from per-provider base images, this lets us specify, eg, oneiric and precise images from each provider. Setup scripts take the provider name as an argument (so each provider in Jenkins can have its own job for easier monitoring). The fetch script takes the base image name (eg, "oneiric") as an argument and gets the oldest matching node from any provider. Snapshot images are created from scratch each time; no more long-running template hosts. Devstack fixed network set to something that doesn't collide with hpcloud. Min_ram is now configurable per-base-image (so we can request servers with a certain amount of ram for each image (in case an image has no swap, or otherwise needs more ram)). SKIP_DEVSTACK_GATE_PROJECT added to the gate script to make testing the script itself during development easier. More robust detection of image URLs in the image update script. On a running devstack node, before running devstack, check to see if there is swap space. If not, assume we're on HPCloud and unmount /mnt and use it for swap.
