There was no option to set the volumeBindingMode for the StorageClass.

Added the option in
nfs-subdir-external-provisioner/charts/nfs-subdir-external-provisioner/templates/storageclass.yaml
and nfs-subdir-external-provisioner/charts/nfs-subdir-external-provisioner/values.yaml as well as updated charts/nfs-subdir-external-provisioner/README.md

This fixes Issue #172
