node_list takes an argument "detail" which adds a rather arbitrary
list of results to the output. This comes from the command-line,
where we're trying to keep width under a certain length; but doesn't
make as much sense here (especially for json).
For dashboard type applications, replace this with a simple "fields"
parameter which, if set, will only return those fields it sees in the
common text output function.
Note, this purposely doesn't apply to the JSON output, as it expected
client-side filtering is more appropriate there. We could also add
generic field support to the command-line tools, if considered
worthwhile.
Add some documentation on all the end-points, and add info about these
parameters.
