Refactor new options into a new config file.

From now on all releases configurations will be available, which will make
easier to test more than two versions upgrade (meaning test upgrades like
g->h->i).
Notes:
 * from-folsom files will not be necessary since we don't test
folsom->grizzly.
 * from-havana files will be added in the next patch(with the change-id follow
change-id Iac520a8de4c3b9f14e2289cfb9b6a50c4ab0ce32).
