This was allegedly included back when simplejson was more performant
that the 'json' library in Python's library. It's additional complexity
that we simple don't need. Remove it. This also allows us to clean up
the tox file significantly.
Note that we must also rename the 'json' module to 'json_utils', as this
was shadowing a built-in library. This is a latent issue that was
highlighted by removing of 'simplejson' imports.
