cooker: no cached in progressbar and add ETA

Rather than updating the progress bar based on the recipe being processed
(whether cached or parsed), consider only parsed recipes.  This reduces the
instability in progress rate introduced by the cached entries, and allows the
ETA to be resurrected and be a bit more useful.
