Relax constraints by default #2004
Description
As a follow-up from #1511, we wanted to relax constraints by default, once we made constraint relaxation compatible with currencies other than euro. We actually ended up making it compatible with other currencies within that same PR, but did not update the default to relax all constraints by default. I think we should.
Alternatively, we could set the default flex-context {"relax-constraints"} when creating new assets. But my preference is to use the load_default of the relax-constraints field for this.
In practice, this will mean users will see the FallbackStorageScheduler in action less often, which is a good thing.
