Subject: [PATCH] xenapi: Use a jeos vm as a template

DevStack was using templating to speed up the setup process with
XenServer. The template already included some devstack customisations,
not just a clean OS. This change modifies devstack behaviour, so that
the template is a simple clean operating system. This makes it easier to
use custom OS as a template, potentially speeding up the tests.
