This does three things:
* Use nice humanized times for update times, to avoid ridiculously
long timestamps consuming lots of horizontal space. Instead of
LAST UPDATE
2017-12-12 12:22:59.994163319 -0800 PST
we now see
LAST UPDATE
1 day ago
* Use the longest config key for the horizontal spacing when the key
exceeds the default alignment size. This avoids individual lines
wrapping in awkward ways.
* Do the same for stack names and output properties.
