Expose guest CPU instruction set extensions

Registered by Alex Xu on 2016-03-28

There isn't a way guarantee the guest can get specific CPU set extensions which
required by image or flavor. This BP aims to expose the guest CPU set
 extenions based on the propose of host capabilities.

    Expose guest CPU instruction set extensions

Please take a look at https://wiki.openstack.org/wiki/File:Resource-capabilities.JPG
https://wiki.openstack.org/w/images/archive/9/92/20160427131036%21Resource-capabilities.JPG
would like to capture resource capabilities in a generic manner, possibly using the CIM namespace, to ensure cloud interoperability. A resource object should have resource capabilities and resource capacity, qualitative and quantitative information.
There is yet another effort to capture accelerator specific information: https://wiki.openstack.org/wiki/Nomad

With each resource capability we need to capture its type, capacity (where appropriate). Items like CPU instruction set it is not a consumable resource, that is not quantity associated with it, unless items
just as virtual CPUS, Field Programmable Gate Arrays (FPGAs) or Non Volatile Memory (NVM) capacity.
