feat(dav): Enable OOO UI and expose enabled via OCP

Makes the feature opt-out now that we have meaningful integrations based
on OOO data. Allows instances still to turn the feature off.

For apps like Mail that build on top of this feature we need to know if
the instance has the feature turned on or off. This is exposed as OCP
API, too.
