[PATCH 2/3] hostname-customization: add initial customization package

["chris.larson via isar-users" <isar-users@googlegroups.com>]

From: Christopher Larson <chris.larson@siemens.com>

This package provides a simple customization package that allows the hostname to
be set in the image. As this value is set from the `HOSTNAME` metadata variable,
it must be set in the metadata.
