This change will leverage the new PreFilterResult to reduce down the list of eligible nodes for pod using Bound Local PVs during PreFilter stage so that only the node(s) which local PV node affinity matches will be cosnidered in subsequent scheduling stages. Today, the NodeAffinity check is done during Filter which means all nodes will be considered even though there may be a large number of nodes that are not eligible due to not matching the pod's bound local PV(s)' node affinity requirement. Here we can reduce down the node list in PreFilter to ensure that during Filter we are only considering the reduced list and thus can provide a more clear message to users when node(s) are not available for scheduling since the list only contains relevant nodes. If error is encountered (e.g. PV cache read error) or if node list reduction cannot be done (e.g. pod uses no local PVs), then we will still proceed to consider all nodes for the rest of scheduling stages.
