From: Jakob Meng <code@jakobmeng.de>

With the '--pretty' option, appctl.py will now print JSON output in a
more readable fashion, i.e. with additional line breaks, spaces and
sorted dictionary keys. The pretty-printed output from appctl.py is not
strictly the same as with ovs-appctl because of both use different
pretty-printing implementations.
