testbot/web: Allow specifying how many days to analyze for the statistics.

Building statistics on the full job retention period may not be what's
needed. Also, the longer the period analyzed the longer it takes to
generate this page.
So let the user specify which period to analyze and default to 7 days, a
reasonable period to get values that are not unduly influenced by
short-term patch storms, but also short enough to reflect current
trends.
