Previously, we still required that clients send "etag" and "size_bytes" keys in their segment definitions. This was done as a way to guard against typos leading to an accidental lack of verification. However, typos should already be caught when we check for extra keys. As a result, the only truly required key is "path". Change-Id: Ie1d8691115f8c68b5a3f3b59317cdab59f9a3fca
