Michael Brown 42bf3b9aa9 [http] Automatically retry request on a 503 Service Unavailable ...

A web server may return a 503 Service Unavailable response along with
a Retry-After header to direct the client to retry the request at a
later time.

The Retry-After header may be a number of seconds, or a full HTTP
timestamp (e.g. "Fri, 7 Mar 2014 17:22:14 GMT").  We have no
reasonable way of parsing a full HTTP timestamp; if the server chooses
to use this format then we simply retry after a fixed 5-second delay.

As per RFC 2616, in the absence of a Retry-After header we treat a
status code of 503 Service Unavailable as being equivalent to 500
Internal Server Error, and immediately fail the request.
