Decide whether we want to archive consensus download times
The consensus-health checker now memorizes consensus download times and displays the last 7 days in a table.
Internally, we're just appending raw download times to a file. If we want to archive them and make them publicly available, we should define some data format, specify/describe the format on the Data Formats page, and put up (monthly) tarballs containing the download times.
Let's revisit this task in a few months (e.g., February 2012?) when we have some data. We might even run a quick analysis on the data first to see if there are interesting trends.
