Submariner 0.12.2 Release

[Daniel Farrell]

Hello,

Submariner 0.12.2 is released!

This is a bugfix release:

• The Globalnet metrics port will now be opened by default when Globalnet is deployed using `subctl cloud prepare`.
• Submariner ServiceExport now has unique condition types to simplify waiting for readiness.
• The `subctl diagnose` command now supports NAT-discovery port validation.
• The `subctl cloud prepare rhos` command will now work properly for nodes to which security groups were added manually.
• The `submariner-operator` namespace is labeled in accordance with KEP-2579: Pod Security Admission Control (default in Kubernetes 1.24)
• to allow the Pods to be privileged.
• The default namespace for the `subctl diagnose` command is changed to `submariner-operator`.
• Submariner pod images are now based on Fedora 36.
• Fix issues related to Globalnet and Route-agent pods due to missing grep in the container image.
• Make secrets for ServiceAccounts compatible with Kubernetes 1.24 onwards.
• Restart health check pinger if it fails.
• Fix intermittent failure when running `subctl diagnose firewall metrics`.

Thank you everyone who contributed!
