enableAutoReload

Optional. If true, we try to automatically reload the document every day (at a time picked by the system). If false or unspecified, we don't try to automatically reload the document. Currently you can only enable automatic reload for documents sourced from a public url, see source field for the source types. Reload status can be tracked in latest_reload_status. If a reload fails, we will keep the document unchanged. If a reload fails with internal errors, the system will try to reload the document on the next day. If a reload fails with non-retriable errors (e.g. PERMISSION_DENIED), the system will not try to reload the document anymore. You need to manually reload the document successfully by calling ReloadDocument and clear the errors.
