* middleware/proxy: add spray keyword When spray is used, the proxy will, when all backend are down, spray to each target. When not used, default to the old defaults: max 1 failure and no spray. These defaults are also used when forwarding queries to another CoreDNS instance. Update the README with the new keyword. * typos * Make MaxFail = 1 again * more reversals
