Log message should be WARN or INFO message when the data bag item "dnsmasq" "managed_hosts" isn't found

👻 Brief Description

Chef logs an ERROR when the data bag item dnsmasq managed_hosts is not found. This data bag item is optional, so it shouldn't be logged as an ERROR. Perhaps a WARN is more appropriate or no message at all.
