keepalive: track request count and bytes sent
I want wire protocol interactions to report the number of
requests made and bytes transferred.
This commit teaches the very low-level custom HTTPConnection class
to track the number of bytes sent to the socket. This may vary from
the number of bytes that go on the wire due to e.g. TLS. That's OK.
KeepAliveHandler is taught to track the total number of requests
and total number of bytes sent across all requests.
