Do you mind re-shaping comments to be compatible with our Go guide?

Can we have comments as full sentences?

Changes
Filter external labels from matchers in
LabelValuesandLabelNamesrpcs.We noticed super high memory spikes in
storegatewayfor the label apis and noticed that if there're matchers store will try to fetch series for postings.When using
prom-label-proxyto enforcetenant_idlabel for example, it's propagating to matchers and so going to slow path, sincetenant_idor any other external label is only presented onmeta.json, all series would have to be fetched resulting in huge memory spikes (~50Gb and more).By filtering external labels from matchers we ensure this won't happen and also filtering the blocks that have those external labels but with different values.
Tested locally and it solved the issue.
