For `puppet apply` to run successfully, outputs of `hostname -f` and `facter fqdn` must match. In a properly configured network environment the outputs should always match, in PoC environment they might not. This patch overrides the FQDN fact to the result of `hostname -f`, which will make `puppet apply` succeed even in PoC environments where DNS is not configured properly.
