We make a point of running defaults in TripleO: if the defaults aren't
generally production suitable, they aren't suitable defaults. If/when
we find a place where there is no sane default, we'll push for having
no default and forcing a choice to be made.
ext3 wasn't a sane default :).
In fact, for CD environments, the ability to set ext3 via config
options means this change is easy to convert into an arbitrary-time
warning period to users, if a cloud needs to.
