Move from Circle CI to Github Actions

[electron0zero]

I see that prometheus moved away from Circle CI to Github Actions in https://github.com/prometheus/prometheus/pull/11235, and similar discussion is going on for statsd_exporter in https://github.com/prometheus/statsd_exporter/issues/604

opened this issue to have a place of discussion for the migration.

if team is okay with the migration, I intend to find some time and start the migration

Sidenote: GRPC tests have been failing on master

Why migrate?

• https://github.com/prometheus/prometheus/pull/11235 shows that prometheus migrated 2 years ago
• Other exporters are also migrating to GitHub Actions
• GitHub actions is one less service to login into, and easy to view CI logs

Possible blockers:

• IPV6 tests in GitHub Actions: https://github.com/actions/runner-images/issues/668 (but we should be able to it get it working like we do it in CircleCI or like this https://github.com/PowerDNS/pdns/pull/12856)

few more datapoints:

• influxdb_exporter moved to GitHub Actions in commit cfec208

• exporter-toolkit moved to GitHub Actions in commit c3bf1e8

• promlens - only has github actions

@electron0zero I am happy to give this issue a shot if you've not started working on it already.
