Tim Burke e7a2b88191 Add http_timeout config option
Otherwise, requests may wait forever for a response.

Now, we will wait at most 10 seconds by default, and allow operators to
adjust that to between 0 and 60 seconds.

This option closely mirrors the http_connect_timeout option in
Keystone's authtoken middleware.
