When dealing with a large number of template instances, for example when launching daemons per VRF, it is hard for operators to correlate log lines to arguments. Add a new with-unit mode which, if available, prefixes unit and user unit names when displaying its log messages instead of the syslog identifier. It will also use the full timestamp with timezones, like the short-full mode.
