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`.

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.

Make single-stat graph take all formatting options.

Single-stat graph should respect any formatting option set at
