NewMaxPDVolumeCountPredicate creates a predicate which evaluates whether a pod can fit based on the number of volumes which match a filter that it requests, and those that are already present.

VolumeZonePredicate evaluates if a pod can fit due to the volumes it requests, given that some volumes may have zone scheduling constraints.
