This release includes a --version flag and adjusts how metadata flags on the command line work.

Cernan now allows the user to specify a comma separated list of metadata tags on startup. This supplants --metric_source in favor of tags. Old cernan default behaviour can be achieved by setting

--tags source=cernan

If you wish to have the above and include a metadata tag foo=bar this would look like

--tags source=cernan,foo=bar
--tags foo=bar,source=cernan
