Alexander Weaver	958fb2c50a	Alerting: Unify structs in Loki client and make them more consistent with Prometheus (#63055 ) * Use existing row struct instead of [2]string, add deserialization helper * Replace Stream struct with stream struct which is exactly the same * Drop unused status field * Don't export queryRes and queryData * Tests for custom marshalling * Rename row fields to T and V for consistency with prometheus samples * Rename row to sample	2 years ago
