Allow identification of OpenStack by Asset Tag

When OpenStack is deployed on some hypervisors (such as VMware
vSphere), cloud-init doesn't detect that it needs to probe the
metadata service because the DMI product name field can't be set
to a field that is recognized by cloud-init.  However, the asset
tag field can be set via flavor extra specs or image metadata.
A similar approach is already used to identify Open Telekom Cloud.

This patch allows cloud init to recognize "OpenStack Nova" or
"OpenStack Compute" in the asset tag field as an indication that
the instance being configured is running on an OpenStack platform.
