For certain volume types (e.g. AWS EBS or GCE PD), a limitted number of such volumes can be attached to a given node. This commit introduces a predicate with allows cluster admins to cap the maximum number of volumes matching a particular type attached to a given node. The volume type is configurable by passing a pair of filter functions, and the maximum number of such volumes is configurable to allow node admins to reserve a certain number of volumes for system use. By default, the predicate is exposed as MaxEBSVolumeCount and MaxGCEPDVolumeCount (for AWS ElasticBlocKStore and GCE PersistentDisk volumes, respectively), each of which can be configured using the `KUBE_MAX_PD_VOLS` environment variable. Fixes #7835
