Planned deprecations in upcoming Lagoon major releases

[tobybellwood]

Here is a placeholder issue to capture deprecations planned for the next major release of Lagoon:

• Deprecate support for Harbor attached to lagoon-core. This has been sup[erseded by the lagoon-remote integration. This
• Removal of all "Openshift" and "Kubernetes" references in the API and database, replaced by "DeployTarget" or similar

I'd like to see these deprecated:

• Workloads able to be deployed as root.
• Core SSH service.
