fix(keystone): update the keystone image to fix project id hashing (rackerlabs#790)

There was an issue with the project id hash which had unforseen breakage
with services like octavia. While the hash length is allowed by the keystone
driver, a hard coded value in the octavia service limits project IDs to only
32 characters.

This change pulls in a new image that will resolve this hashing issue so that
new projects don't encounter this issue.
