* Add /paths page that shows rollup metrics by path
* Clean up ApiHelpers a bit
Adds ability to sort by column in the tabbed metrics table (to make a TabbedMetricsTable sortable, set sortable={true})
Adds a page, accessible via /paths that shows a table of all paths, with their request/success/latency metrics. I haven't exposed it in the sidebar as it doesn't have design treatment.
