add page load perofrmance metrics to understand performance / latency / success rates of large uploads

Project Member Reported by bmcquade@chromium.org, Sep 10 2016 
n  bug 524258 , it was mentioned that ssl socket buffer size has a significant impact on upload performance. This makes sense. Upload performance is important for a subset of pages, so it'd be beneficial to measure this directly. We'd want to measure the distribution of upload latencies, as well as the number of successful vs aborted uploads.

This isn't particularly high priority - we have other more important metrics to work on - but it seems like something we should measure eventually.

What is the end point you are thinking? I am working on a related issue as part of triage duty ( issue 571250 ). We could either
1. Wait until the response is received from the server
2. Wait until we've finished writing all our data to the socket.

(2) is impacted by the kernel buffer size but will likely be less noisy than waiting for the response of a large upload (maybe the server does synchronous processing of the data, etc.).
