Add standard puppet metadata.json and remove Modulefile

This module has been split out from system-config, and additional
files are required to create a proper puppet module.

Some of the files are described in the spec:
http://specs.openstack.org/openstack-infra/infra-specs/specs/puppet-modules.html
