ratelimit use wrong HTTP error code (should be 429, not 498)

[Donagh McCabe]

According to http://tools.ietf.org/html/rfc6585 the appropriate error code for a container being rate-limited is 429, not 498.

This RFC post-dates when the ratelimit middleware was written, hence the missmatch.

Fix proposed to branch: master

Rate limiting in swift was implemented before the above rfc was proposed. Changing the rate-limit in the current API would break clients, and so would not be advisable. We have started collecting things like this on the following page that we could implement in the next rev (possibly v1.1) of the API.

Closing as wontfix since we can't do it without a breaking API change. The change is noted on the referenced wiki page, though, so this bug isn't needed any more.
