>
> Downgrade must determine, or be passed, the targeted downgrade stack. In the
> event that the downgrade is moving to a version that is different than the
> current desired (as determined by the Cluster desired stack version),
> Downgrade must remove those configurations.
> After which, the most current configs for the targeted downgrade version
> should be re-set as the current for the cluster.
> In addition, the ConfigureAction must be augmented to understand that when it
> is being invoked by a downgrade, and is across stacks, that it may be
> no-opping as it reverts
