Bug 1059317 - Move talos stats to a separate panel

This patch creates a new panel dedicated to the talos results.
The way the talos panel is enabled and disabled is a bit hacky, but for now we don't have any other exception like this. We may want to think about a more elegant solution if we face another case like this in the future
I'm probably missing a piece of the puzzle... afaiu all the jobs grouped under the 'Talos performance' job group are involved. At the moment there are 17 jobs under the Talos performance group, do you know another way to select them?
