Ed Welch	c8760f31e2	Loki: Remove validation of matchers when performing label values lookup. (#8224) ... the curren validation fails on != style matchers when they are the only matchers present, requiring at least one `=` matcher. However for looking up label values in TSDB, by design it uses a `desired_label != ""` style query, as such it should be allowed to also include these as matchers. Additional matchers on this Label Value queries typically only exist with LBAC headers adding additional labels.
