Currently, the list of supported vGPUs is populated automatically within the Nova playbook when the /sys/class/mdev_bus folder is present. This will populate the `enabled_vgpu_types` variable with the full list of vGPUs that are supported by default, with only the first one listed being used. This change provides the ability to define a new variable `nova_enabled_vgpu_types` that will populate the enabled_vgpu_types config option. It also adds the ability to map vgpu types to PCI addresses in line with Ussuri updates to provide multi-vGPU support. Change-Id: Icc0c2cd896d4c9a01601d4d733f38443ad8400d4
