Upgrade ClusterManagementAddOn and ManagedClusterAddon API to v1beta1

[haoqing0110]

Describe the enhancement
A clear and concise description of what the enhancement request is.

The Addon configurations and install strategy features have been added for years. Create this issue to trace the API change need to do in the future:

• ClusterManagementAddOn deprecated field to be removed in v1beta1:
  • spec.addOnConfiguration
  • spec.supportedConfigs rename to spec.defaultConfigs

Based on https://github.com/open-cluster-management-io/enhancements/tree/main/enhancements/sig-architecture/81-addon-lifecycle
ClusterManagementAddOn should remove SupportedConfigs, adds DefaultConfigs section to list the default add-on configurations. (Today SupportedConfigs is already and only used to set default configs, the actual supported configs are hard coded in the addon's code)

• ManagedClusterAddon deprecated field to be removed in v1beta1:
  • spec.installNamespace
  • status.addOnConfiguration
  • status.configReferences.name & status.configReferences.namespace
  • status.configReferences.lastObservedGeneration
• ManagedClusterAddon deprecated labels to be removed in v1beta1:
  • "open-cluster-management.io/addon-pre-delete"
  • "addon.open-cluster-management.io/hosted-manifest-location"
• ManagedClusterAddon deprecated finalizer to be removed in v1beta1:
  • "cluster.open-cluster-management.io/addon-pre-delete"
  • "cluster.open-cluster-management.io/hosting-addon-pre-delete"
  • "cluster.open-cluster-management.io/hosting-manifests-cleanup"

@Ankit152 Thank you for your interest in this! I just updated some more details in the description.
There will be a lot of changes to the API upgrade, and we will have some discussions and evaluations next, as well as log some subtasks. You are welcome to pick out some subtasks that interest you and contribute.

[Ankit152]

Sure. I would definitely work on it. I will reach out to you on slack. Thanks!

This task is removed from v1.0.0 release preparation, due to too much API changes and impact. The further discussions will still happen in the future.
