Multiple GPU (PC, LAN, Cloud) support for DeepPRIME

The new DeepPRIME is great. However at present it is limited to support a single GPU. DeepPRIME should be expanded to use all available GPU’s on a single PC, available GPU’s on a local LAN or even GPU’s from the Cloud. is a good example of this approach for accelerating Blender projects.

Users of 2013 Mac Pros particularly need this, as replacement GPUs and eGPUs are not available as an upgrade path.
