Submariner 0.4.0 Release

[Daniel Farrell]

Hello,

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`.
