Epic Goal

Add DeviceManager and DynamicResourceAllocation Support

Why is this important?

Dynamic resource allocation is an API for requesting and sharing resources between pods and containers inside a pod such as accelerator cards. This is an internal feature that most users do not need to interact with and is enabled via a FeatureGate `DynamicResourceAllocation`

[OCPSTRAT-408: Dynamic Resource Allocation API](https://issues.redhat.com/browse/OCPSTRAT-408) introduce this as a tech preview for 4.13. It is enabled via feature flag today, and is still in alpha.

> DynamicResourceAllocation false Alpha 1.30 –

For this Epic, and to claim support and align with our roadmap, we need to QE the feature in 4.19 timeframe.
