[NOJIRA] Migrate circle-ci to github action

[edznux-dd]

What does this PR do?

• Adds new functionality
• Alters existing functionality
• Fixes a bug
• Improves documentation or testing

Please briefly describe your changes as well as the motivation behind them:

This repo predates github action I believe, and circle-ci isn't a widely used CI provider at datadog. Migrating to github action allows us to simplify the deploy process and consolidate it with other repositories, tooling etc...

Code Quality Checklist

• The documentation is up to date.
• My code is sufficiently commented and passes continuous integration checks.
• I have signed my commit (see Contributing Docs).

Testing

• I leveraged continuous integration testing
  • by depending on existing unit tests or end-to-end tests.
  • by adding new unit tests or end-to-end tests.
• I manually tested the following steps:
  • x
  • locally.
  • as a canary deployment to a cluster.

To fix the following error

I don't think I want to fix this error this way: it install a tool that isn't used in the job (the unit tests and e2e test don't run golangci-lint), so this takes times for no real reasons.

I think the correct fix would be in the makefile instead
