Requests to /page/html/{title} fetch the latest revision known to RESTBase. This is normally up to date, but it would be nice to be able to ask for a 'really up to date' version.

We use Cache-Control: no-cache headers to refresh the rendering of individual revisions already (at /page/html/{title}/{revision}). We could consider adding similar support at /page/html/{title}, which

1. refreshes the revision metadata (similar to a no-cache request for revisions), and
2. re-renders the page content, or otherwise makes sure that the render is up to date.

For 2) we might be able to leverage information returned from the revision metadata request, in particular [page_touched](https://www.mediawiki.org/wiki/Manual:Page_table#page_touched).
