Merge lp:~cjwatson/lazr.restful/pformat-value-list into lp:lazr.restful

[Colin Watson]

Make pformat_value iterate into lists.

This causes pprint_entry and pprint_collection to print text string representations in the Python 3 style.

Launchpad will need a small patch when integrating this (https://paste.ubuntu.com/p/Vtr9jG9tMv/).
