Mutiple VGPU types per compute node

Registered by Sylvain Bauza on 2020-01-16

For the moment, it's only possible to support only one GPU type per compute service. Operators can support multiple types if they use separate GPU types per compute node and then use aggregates for grouping per type, but they would ideally also like to have a compute service supporting two or more different types if they have more than one physical GPU.
