DRA: ResourceClaim Support for Workloads

[nojnhuh]

Enhancement Description

DRA APIs can currently express requests for devices that are shared among individual Pods or requests that are replicated for each Pod requesting the same ResourceClaimTemplate. This enhancement describes a way for Workload objects (#4671) to express ResourceClaimTemplates that replicate one ResourceClaim per Pod group, and for Pods to reference the ResourceClaim created for its Pod group replica. This will allow Pods within one instance of a group to share a set of devices that is distinct from the devices shared by Pods in another group.

• One-line enhancement description (can be used as a release note): Pods in a Workload API Pod group can share ResourceClaims replicated for each instance of the Pod group.
