trooper-o-matic: Add patch attempt timeline view to CQ graphs

This change adds an additional view mode to the CQ graph patch summary lists
to view the patch attempts on a timeline with indications of success or
failure with failure reasons.

This feature should make it easier to identify clusters of failures in time
across multiple patch attempts e.g. all try jobs failing to trigger for 20 minutes.

LGTM, thanks Alan!

I didn't really go into much detail, since I'm not that familiar with Javascript
/ polymer, but the demo works, and it'll be quite useful for diagnostics, so I'd
say let's deploy it.

lgtm

+seanmccullough, who should probably start taking over the polymer side of these
reviews.

This won't bind correctly if you change a member of attempt (e.g.
attempt.success or attempt.durations.total), but don't actually replace the
whole attempt object since the binding is based off object identity.
