Submariner 0.7.0 Release

[Daniel Farrell]

Hello,

Submariner 0.7.0 is released!

This release mainly focused on adding support for StatefulSets in Lighthouse for service discovery and adding new subctl commands to benchmark the network performance across clusters.

• Lighthouse enhancements/changes:
• Added support for accessing individual Pods in a StatefulSet using their host names.
• A Service in a specific cluster can now be explicitly queried.
• Removed support for the `supercluster.local` domain to align with the Kubernetes MultiCluster Service API.
• Added new subctl benchmark commands for measuring the throughput and round trip latency between two Pods in separate clusters or within the same cluster.
• The data path is no longer disrupted when the Globalnet Pod is restarted.
• The Route Agent component now runs on all worker nodes including those with taints.

When upgrading to 0.7.0 on a cluster already running Submariner, the current state must be cleared:

• Remove the Submariner namespaces: `kubectl delete ns submariner-operator submariner-k8s-broker`
• Remove the Submariner cluster roles: `kubectl delete clusterroles submariner-lighthouse submariner-operator submariner-operator:globalnet`
