run: prewarm cache before run
I started seeing benchmark failing because `hg debugupdatecache` covers more data in some core changesets (so taking extra time to warm some cold cache). Instead we perform an extensive cache warming in the preparation steps. Once the cache are warm the `hg debugupdatecache` run are "fast". See inline documentation for details. We also introduce a way to skip this step as it might be slow.
