With addition of storage v2 versions and v2 API it's now less trivial
to rely on overrides for storage configuration, which most likely will be
needed regardless, since v1 storages are incompatible with /v2 API,
and latter one gets disabled whenever v1 storage is in use.
With that there's no dummy storage in /v2 for testing purposes, so
we are not able to have any reasonable default out of the box.
