The configuration files for the swift proxy and storage server were
getting their permissions changed from 0640 to 0644 due to the missing
mode on the concat resource for these files. This change defines the
permissions for these files to be 0640 to prevent unauthorized reading
of sensitive information that may be contained in these files.
