API v2: pods: fix two incorrect return codes
1) /pods/<X>/exists - is documented to return 204, and that's
the correct value, but until now it has been returning 200.
2) /pods/create - return 409 (conflict), not 500, when pod
already exists
Also: in WriteResponse(), if code is 204 (No Content) or 304
(Not Modified), emit the status code only but no content-type
headers nor content.
