Update the system-config manifest to support the simplifying changes
made in the puppet-infracloud module.
This patch will require updates to hiera. We need keys
hpuswest_ssl_cert_file_contents and ssl_key_file_contents added, and
hpuswest_ssl_cert_file_contents must be in the 'infracloud' hiera group
since it is shared to the compute nodes.
