restore_cached_data plugin re-extracts metadata when
assigning already cached files, i.e. when the attachment has been retained
on validation errors or assigned from a direct upload. In both cases you
may want to re-extract metadata on the server side, mainly to prevent
tempering, but also in case of direct uploads to obtain metadata that
couldn't be extracted on the client side.
It uses the
refresh_metadata plugin to re-extract metadata.
