[Mooney, Sean K] 
I know there is a bad memories when I metion CIM (http://www.dmtf.org/standards/cim)
for many on the nova team but if we are to use standard names we should probably
actually assess are there existing standads that we could adopt instead of defining
our own standard names in nova for the resources. 
For example http://schemas.dmtf.org/wbem/cim-html/2/CIM_ProcessorAllocationSettingData.html
Define the name for different instcution set extentions for example avx is DMTF:x86:AVX.
Some work has been done in glance to allow importing cim metadata from ovf files also
https://specs.openstack.org/openstack/glance-specs/specs/mitaka/implemented/cim-namespace-metadata-definitions.html

while I don’t think using the full cim information model is useful in this case using the name would be
from an inter-operability point of view as we not only would have standard names in openstack but those names
would conform to an existing standard.

We could still allow custom attribute but is see value in standardizing what can be standardized.
