Cloned from launchpad blueprint https://blueprints.launchpad.net/oslo/+spec/improve-formatting-cliutils.

Description:

In my work to include the Event API into the python-ceilometerclient, I noticed that the way we do formatting for fields when printing lists is a bit awkward in that, for the supplied formatter, it passes the entire object (Like an Event object) in rather than the value to be formatted (a dict of traits). I propose that we change this to pass in the actual fields value.
