* Explore: Remove datasource testing on selector - datasource testing gets in the way of fast query iteration: switching between datasources can take seconds - it should not be explore's duty to test datasources in the first place - removed the concept of datasourceError in Explore, should not be its concern - datasource erorrs will express themselves in query errors just fine - connection errors are still bubbled up - removed reconnection logic from explore, should not be its concern - missing labels in loki are still "visible" via an empty label selector - Loki and Prometheus treated connection errors differently than other datasources, making sure to pass through the original error message * Show datasource error in query field for prom/loki/influx * Removed connection test case, fixed disabled state
