@mx-psi I asked a review from you because of the changes to other dependencies that this bump brings. One dependency in particular seems to be the prometheus client. Looking at the changelog it seems that v1.12.0 actually adds support for Go 1.17 so maybe we actually need it ?

I don't know which Prometheus features we use in the Agent, that is a question for Agent Core. If we use the feature updated in prometheus/client_golang#955 I think we should update indeed. In any case, I think this PR leaves us better (or at least not worse) than we currently are, so I will approve it!
