[research] Test GPU support in workspaces

[csweichel]

Is your feature request related to a problem? Please describe

Kubernetes can make GPUs available in pods. Can those GPUs be used from within a Gitpod workspace?

Describe the behaviour you'd like

GPUs should be possible to use if the underlying cluster supports it.

How

Can we run Gitpod workspaces with GPU? Try changing the config map in-place for ws-manager and workspace-templates first, before any actual code changes. The expectation is that if code changes are needed, they'll be throw away, and not actually merged back tomain.

Intended output

Note: this is just a research task. We want to know where we stand today for scheduling workloads that need GPU, and how well Gitpod runs on them.

Questions

1. Does Gitpod work on a node supporting GPUs? How well does it work?
2. Can we use all of the cores of the GPU?

@lucasvaltl I've scheduled this work, as it'll require a code change for Workspace components.

@lucasvaltl @corneliusludmann I've removed Team Workspace from this issue, and added to the self-hosted inbox.
