manifest: make manifestlog use it's own cache
As we start to make manifestlog the primary manifest source, the dependency on
manifest.manifest will cause circular dependency problems. Let's break this
dependency by making manifestlog use it's own cache. In a near future patch we
will remove the previous manifest cache so we're not duplicating it.
