Move from Circle CI to Github Actions

[electron0zero]

I see that prometheus moved away from Circle CI to Github Actions in prometheus/prometheus#11235, and similar discussion is going on for statsd_exporter in prometheus/statsd_exporter#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?

• Move to github actions prometheus#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: IPv6 on GitHub-hosted runners actions/runner-images#668 (but we should be able to it get it working like we do it in CircleCI or like this Enable ipv6 for actions running on docker containers PowerDNS/pdns#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.
