util: implement sortdict.insert()

As flagged by pytype (reported via Matt Harbison, thanks). This was
broken by bd0fd3ff9916 (util: rewrite sortdict using Python 2.7's
OrderedDict, 2017-05-16). We actually call insert() on
namespaces.py:100, but we clearly don't have test coverage of that an
no users have reported it AFAIK.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
