Submariner 0.12.3 Release

[Daniel Farrell]

Hello,

Submariner 0.12.3 is released!

This is a bugfix release:

• Image version hashes are now 12 characters long, avoiding possible collisions between images.
• Stop using cluster-owned tag for AWS cloud prepare, fixing problems with Submariner security groups left over after uninstallation.
• Support overriding the MTU value used in TCP MSS clamping, allowing fine tuning of MTU when necessary.
• CNI interface annotations created by Submariner are now removed during uninstallation.
• Bump x/text to address CVE-2021-38561 and CVE-2022-32149.
• Diagnose now validates if the `OVNKubernetes` CNI is supported by the deployed Submariner.
• Set `DNSPolicy` to `ClusterFirstWithHostNet` for pods that run with host networking.
• Service Discovery now writes the DNS message response body when it is not a `ServerFailure` to avoid unnecessary client retries.
