a1c32702,736cf54a, and38787d0fremove uses of `simplejson` from various parts of Swift in favor of the standard libary `json` module (introduced in Python 2.6). This commit performs the remaining `simplejson` to `json` replacements, removes two comments highlighting quirks of simplejson with respect to Unicode, and removes the references to it in setup documentation and requirements.txt. There were a lot of places where we were importing json from swift.common.utils, which is less intuitive than a direct `import json`, so that replacement is made as well. (And in two more tiny drive-bys, we add some pretty-indenting to an XML fragment and use `super` rather than naming a base class explicitly.) Change-Id: I769e88dda7f76ce15cf7ce930dc1874d24f9498a
