Support the vcpu-topology image metadata options inside XenAPI

Registered by John Garbutt on 2013-11-20

There is a proposal to support specifying the max threads, cores and sockets on an image:
https://wiki.openstack.org/wiki/VirtDriverGuestCPUTopology

In XenAPI we certainly have the cores-per-socket setting:
http://support.citrix.com/article/CTX126524

We should consider support the use case where a windows guest might request 8 vCPUs but have a max-sockets=4 so we can offer that guest those 8 vCPUs grouped into 4 sockets each with 2 cores.

At a later date we may need to expose more of the NUMA architecture, but for now, lets cover the above case.
