Upgraded RPM Calculation Support (Take 1)

This patch begins the work on updated RPM calculations using
the httptrace infrastructure. Because we are still not able
to break out the TLS handshake time due to upstream bugs, there
are some workarounds in place. However, the numbers appear much
more sane.
