Title: Fix unnecessary NetworkManager stderr output.

If `nmcli` exists but NetworkManager is not running (or not being used to manage networking), then the `dhcp_servers` fact generates the stderr output `Error: NetworkManager is not running.` on each run of Facter/Puppet, generating unnecessary stderr output, cron emails, and/or puppet report output.
