Submariner 0.4.0 is released!

This release is mainly focused on Submariner's Libreswan cable driver implementation, as well as standardizing Lighthouse's service discovery support with the Kubernetes Multicluster Services KEP.
  • Libreswan IPsec cable driver is available for testing and is covered in Submariner's CI.
  • Lighthouse has been modified per the Kubernetes Multicluster Services KEP as follows:
    • A `ServiceExport` object needs to be created alongside any `Service` that is intended to be exported to participant clusters.
    • Supercluster services can be accessed with `<service-name>.<namespace>.svc.supercluster.local`.
  • Globanet overlapping CIDR support improvements and bug fixes.
  • Multiple CI improvements implemented from Shipyard.
  • CI tests are now run via GitHub Actions.
  • Submariner-operator now completely handles the Lighthouse deployment via the `ServiceDiscovery` CRD.
  • `subctl verify` is now available for `connectivity`, `service-discovery` and `gateway-failover`.

Thank you everyone who contributed!
