Matthew Oliver f4d3facdf4 Treat 404s as 204 on object delete in proxy ...

This change adds an optional overrides map to _make_request method
in the base Controller class.

  def make_requests(self, req, ring, part, method, path, headers,
                    query_string='', overrides=None)

Which will be passed on the the best_response method. If set and
no quorum it reached, the override map is used to attempt to find
quorum.

The overrides map is in the form:

    { <response>: <override response>, .. }

The ObjectController, in the DELETE method now passes an override map
to make_requests method in the base Controller class in the form of:

    { 404: 204 }

Statuses/responses that have been overridden are used in calculation
of the quorum but never returned to the user. They are replaced by:

    (STATUS, '', '', '')

And left out of the search for best response.
