Lite

Work to accommodate the everest ovf properties. Relocated the timezone module.
rather than reboot, here I've just got a custom property:

<Property oe:key="custom.network" oe:value="priority=after always=1 action=ifdown%20-a%20&&%20ifup%20-a ;; priority=after always=1 action=hostname%20-F%20/etc/hostname"/>

We could either do the same here, or just bake that into the network module as an everytime item.
