I was looking into the way that SOM is set up earlier this week; I think that this will be a good thing to do to set up for any future web UI of Tricium (even though web UI for Tricium will be quite simple and isn't very critical right now).

Add ChopsUI header in Tricium web UI

Since there's not any functionality in the web UI at present,
we can hold off on adding actual Polymer elements specific
to this app.

I'll keep this open until:

 - there is at least 1 custom element in the web UI
 - there is a lint/test process for any custom elements

Changing priority since I'd like to do this before adding a feedback stats page (bug 845530). There are several other web apps to look at in infra when deciding how to do this; I think for now I may want to use SOM as a model of roughly how to do this, although of course the Tricium frontend should be much simpler than SOM.

[tricium] Change the run page to fetch Progress JSON

This changes removes run.go and changes the run page
just fetch data from the Progress RPC endpoint.

The run page was made partly for debugging and partly
to provide a link that comments can link to for more
details about a Tricium run.

I think that the data from the Progress RPC response
should probably be sufficient.

Next changes to do after this include:
 - Set up a polymer elements directory with tests
 - Add an element for showing run progress
 - Add a main app entry point element which routes
   based on path
 - Add an element for showing tables or charts of
   "not useful" over time

[tricium] Simplify template usage

The previous templating logic was good for a website with multiple template
pages, but the plan for the tricium front-end is to use a single main page
with different views depending on path, with routing done on the front-end.

With this in mind, template usage can be simplified, and the templates
directory can be replaced with a single index.html.

This is based on the model of some other apps in the infra repository
such as sheriff-o-matic and tree-status.

[tricium] Add an initial UI set-up using lit-element

Differences of the lit-element version from the Polymer 3 version:

Data binding features of lit-element are less than for Polymer,
so some Polymer elements are less useful, e.g. app-route and iron-ajax.
These can be replaced and done in other ways, e.g. the pwa-helpers
package has a simpler router.
