Improvements to DevStack's XenServer scripts
I have ensured:
- template gets re-used on second run
- template includes XenServer tools, and custom user accounts
- take snapshot before first boot, for easy re-run
- make host_ip_iface work with either eth2 or eth3
- make ssh into domU checks looser
- above is all ground work for improved jenkins tests
- added some more comments to make it scripts clearer
