Allow DirectDeploy for preproduction and production

Please enable the DirectDeploy option for preproduction and production environments. Currently it is only available for integration. I understand that the goal is for preproduction to mirror production as closely as possible and for both environments to have very robust validation procedures, but there are certain scenarios where a direct deployment to those environments would be beneficial. For example, we recently had a production deployment which required some additional stylesheet changes that were only discovered after the release to production was complete. In this type of scenario, there is no need to create a new slot for the deployment. Allowing the direct deployment option for all environments would give us the power to better manage releases.
