We are currently doing some nasty things to report the coverage. Coverage results are not stored anywhere and one never knows how the coverage changed from on PR to another.

I propose to integrate with https://codecov.io, which is a great and free service for monitoring and reporting code coverage.

It is easy to integrate with GH actions and with Go build-in coverage tooling.

I can't do the integration myself because someone with admin rights needs to log into codecov and do the setup.
