Remove automation_base.xml and update all of the automation specs.

We are no longer using automation_base.xml so deleted it shall be.  However, doubly bad is that all of the automation specs were using that, so basically it wasn't testing anything of importance.

@tinaafitz Please review.  Note that there are still 2 failures for power_off and unregister_from_provider, which refer to the MiqQueue and I can't seem to fix.
