Around guarding enabling and disabling MDT. i.e. if someone enabled MDT and after few commits disables MDT and then re-enables it, we should re-bootstrap the MDT. So, we were wondering if we can add the "metadata.enable" property to table config. So, when someone disable MDT, we can clean up the MDT right away. We don't leave any trails and don't need to worry about when the user will re-enable it back.
