[autoroller] All commits in updates(), only roll interesting ones.

Previously `updates` would only include the 'interesting' updates, which
meant that the new autoroller algorithm skips over chunks of the repo
history. If multiple repos have chunks of non-interesting history, the
autoroller can end up not proposing any good candidates.

This CL simplifies the repo interface by having `updates()` always
return the full list of commits, but adds a new field to the
CommitMetadata which indicates that a given commit was `interesting`.
This way the full history of every repo is available when picking
candidates (e.g. for `CommitList.advance_to`), but find_best_rev will
only consider rolling to interesting commits.
