Newer version of Local Path Provisioner in samples (#6437)

To make it less confusing for users who uncommented whole block of
local path provisioner [1] the samples should point at least to
version 0.0.3 which supports helper image [2] configured by
local_path_provisioner_helper_image_repo variable. As 0.0.3 is a bit old
samples could point to current newest release 0.0.14.
