Log GOVUK-RequestId

It’s helpful when comparing timings to see which request went from one
data centre to another and where any slow parts might be.

This also adds tracing by passing on the Request-Id and GOVUK-Request-Id
headers on to backdrop and stagecraft, via extending the options passed
to `fetch`.

Set the width of "more info" for small modules

When a module is only half or a third of the width of the page (cols2
or cols3), its "more info" is set to a third of that width.

This commit adds Sass so that the info on a small module is the size
of the module.

Remove comment about client_instance script

The script attribute of a client_instance is tested in the view,
for example in body-end.html:

    <% if (model.get('script')) { %>

It can be set to false to disable including of our rather large
JavaScript assets.
Remove query params when using Stagecraft API

When we pass a path onto Stagecraft to find out information about
a dashboard, we don't want to include any query parameters because
this will cause Stagecraft to return a 404.

Single-stat graph should respect any formatting option set at

Inital part of the new column module.

Can be configured to use max-bars

It's basically the same as a bar-chart-with-number for now however it groups a collection and does some other bits to the collection to get the x-axis working in bar charts.

Updated the controller_map to use the new column module.
Tests for the column visualisation.
Added the ability to add a label to the x-axis of the graph.
