 * ITFlow - Database update to version 3.6.8 (from 3.6.7)
 * Included by admin/database_updates.php - do not access directly
 *
 * RMM alerts open tickets (functions/rmm.php):
 *   rmm_providers.rmm_provider_alert_level - which alerts open tickets: '' none, error,
 *     warning (and errors) or info (every one); rmm_provider_alert_category_id - the ticket
 *     category they get; rmm_provider_alerts_since - when it started watching (NULL until the
 *     first look, which takes the alerts already open as known); rmm_provider_alerts_at and
 *     rmm_provider_alerts_note - when it last looked, and what went wrong if it didn't work
 *   rmm_alerts - one an alert ITFlow has seen: the device it is on, what it is about there (a
 *     check, a task, the device not checking in), its severity and message, when it was raised
 *     and cleared, and the ticket it is on - 0 when it was already open before ITFlow watched
 *
 * Re-runnable: the table and each column are made only where they aren't there yet.
