Customer testing has show fwaas v2 to be rather buggy, revert to running with fwaas v1 now. The fwaas project seems to be lacking maintainers currently, see whether that situation improves until the next cycle. Otherwise we may need to drop the service completely, as fwaas v1 has been removed for Train. Change-Id: I5d1af49a56a86a66a1d2509b4ca306b6e0cdf77c
