Render long output in cli gracefully

[Maciej Kwiek]

This bug was fixed by removing 'changes' from cli output: https://bugs.launchpad.net/fuel/+bug/1373471 but when some fields in cli listings are very long, you can end up with malformed output.

You can reproduce it by assigning an absurdly long label to nodes:

fuel2 node label set -l <label-longer-than-your-screen-is-wide> --nodes-all
fuel2 node label list

I think that this bug can be marked as Won't Fix, because now it is possible to control long output gracefully by '--max-width' and CLIFF_MAX_TERM_WIDTH envvar from cliff.
