bpo-33504: Migrate configparser from OrderedDict to dict. (#6819)

Browse source 
With 3.7+, dictionary are ordered by design.  Configparser still uses
collections.OrderedDict, which is unnecessary.  This updates the module
to use the standard dict implementation by default, and changes the
docs and tests to match.
