Migrations: * add a new column alert_group_idx to alert_rule table * add a new column alert_group_idx to alert_rule_version table * re-index existing rules during migration API: * set group index on update. Use the natural order of items in the array as group index * sort rules in the group on GET * update the version of all rules of all affected groups. This will make optimistic lock work in the case of multiple concurrent request touching the same groups. UI: * update UI to keep the order of alerts in a group
