Value Statement

As an ACM policy user, I would like to use Placement instead of PlacementRule in the create policy wizard since PlacementRule is being deprecated.

Definition of Done for Engineering Story Owner (Checklist)

• Change the default in the create policy wizard to use Placement instead of PlacementRule. Both are currently supported and will remain so.
