When the destination service returns a hint that an endpoint is another
proxy, eligible HTTP1 requests are translated into HTTP2 and sent over
an HTTP2 connection. The original protocol details are encoded in a
header, `l5d-orig-proto`. When a proxy receives an inbound HTTP2
request with this header, the request is translated back into its HTTP/1
representation before being passed to the internal service.

Specifically proxied bodies would make use of an optimization in hyper
that resulted in the connection not knowing (but it did know! just
didn't tell itself...) that the body was finished, and so the connection
was closed. 0.12.7 includes the fix in hyper.
As part of this upgrade, the keep-alive tests have been adjusted to send
a small body, since the empty body was not triggering this case.
