* fix viz * add datasource picker on query rows in mixed mode * add timerange, handle add/remove queryrunners * multiqueryrunner test * trying things out. * adding another test to verify running a induvidual query runner will update multirunner. * cleaned up tests a bit. * draft version working ok. * fixing so we base the refId from request targets. * reenable adding expression * layout fixes for alerting page * some cleanup * cleaning up code that we won't use * changed so we don't display the time range if params not passed. * remove unused things in querygroup * changed button to type button. * removed timerange from dataQuery and removed multiquery runner. * minor refactoring. * renamed callback function to make it more clear what it does. * renamed droppable area. * changed so we only display the query editor when selecting threshold. * removed the refresh picker. * revert * wip * extending with data query. * timerange fixes * it is now possible to add grafana queries. * removed unused type. * removed expect import. * added docs. * moved range converting methods to rangeUtil. * clean up some typings, remove file * making sure we don't blow up on component being unmounted.
