Allow scheduling of SRIOV daemonset pods with affinity

1. Proposed title of this feature request
Allow scheduling of SRIOV daemonset pods with affinity
2. What is the nature and description of the request?
Enhance the options for scheduling the SRIOV daemonset pods on nodes within the cluster. Currently, our only option for determining pod placement is through NodeSelector which has limited usability.
3. Why does the customer need this? (List the business requirements here)
By improving the pod placement of the daemonset pods we can provide more flexibility to the end-user. For instance they can utilize matchExpressions which would allow for scheduling the pods using node labels in an "OR" fashion. This is not something that can currently be achieved through NodeSelector.
4. List any affected packages or components.
