Tim Burke 9eee29d2e4 tempurl: Support sha256 and sha512 signatures
Up the default to sha256 since

* the proxy has supported (and defaulted to allowing) it for four years
  now, and
* Rackspace has supported it for even longer.

Include a note in the --help about older clusters likely requiring sha1.
