add telemetry (#83)

Enables telemetry during CI runs. This is done by parsing GitHub Actions run log metadata and should have no impact on build or test times.

It's a little bit silly on this repo, since it is just metapackages. I am putting this PR up for completeness, but I also think it would be fine to omit telemetry on this repo.
