Previously an unreadable file (e.g. /etc/ipt-firewall is 0750 after the
role ran) silently produced almost empty host_vars. The script now exits
with an error and writes nothing. --from-dir reads the conf files from a
local directory, e.g. fetched with ansible using the vaulted become
password.
Add host_vars for cl-test.oopen.de (fw_manage_config: true).
