Switch scheduler drivers to load based schedulers
Cloud deployed at scale most likely will use these scheduler drivers because they allow a fairer resource allocation compared to chance schedulers (which randomly place resources on the hosts). Because of their importance, it's only wise to test them in the gate on a continuous basis, so that we do not get surprised by accidental regressions. Rather than pushing this down through devstack-gate/project-config patches, this chance alters the default of the scheduler drivers, so that users can also pick these up out of the box. This means that after an upgrade they would observe a change in the scheduling behavior, if they relied on the default config.
