Delete unnecessary PrerenderRelType enum

We can just use WebPrerenderRelType directly and we won't need to worry about
them getting out of sync.

Fix results.ResultsGrid unit test

Polymer initializes the attribute values to the empty string, not
undefined. This may be a change with a new version of Polymer, hence
Eric using this value and having it work.

Sheriff-o-matic should have an awesome transition

Add embedded flakiness dashboard to sheriff-o-matic

Create a new Polymer widget for the embedded flakiness
dashboard.

Sadly the height isn't always right, as the underlying
flakiness dashboard code doesn't always post us a message
with the proper height. This issue existed in the previous
version as well.
