[EPIC] Day 2 Ops for Imported RKE2/K3S Clusters

[richard-cox]

RFD: https://github.com/SUSE/rancher-architecture/pull/38
rancher/rancher#54228
Support day 2 operations for imported rke2/k3s and CAPI clusters

• etcd snapshot create + restore
• certificate rotation
• encryption key rotation

Currently

these are managed via updating the v2prov provisioning.cattle.io cluster.

• rkeConfig.etcdSnapshotRestore|etcdSnapshotcreate|rotateEncryptionKets|rotateCertifcates props

the same provisioning cluster object also contains configuration

• automatic snapshots
• snapshot location
• metrics

Changes

These apply to all supported types

• v2prov clusters
  • old method will continue to be supported, but be deprecated
  • migrate from old method to new method needs to happen, but doesn't have to be in same milestone
• imported rke2/k3s clusters
• CAPI clusters (not v2prov capi clusters, these should be covered by first point)

Changes

• create/edit clusters
  • all types
    • operation config
    • stored in prov cluster for v2prov, otherwise mgmt cluster
    • object is the same regardless of which cluster type config is stored inmap?
  • mgmt cluster type
    • option to enable day 2 operations. default value is imported-cluster-day-2-operations-default setting
• operations
  • types
    • etcd snapshot create + restore
      • for imported and capi clusters add snapshots tab to detail page
        • list v1/rke.cattle.io.etcdsnapshots (with same columns as v2prov)
          • create snapshot via new operation
            • visible if user can create the operation CR
          • delete snapshot as before
            • visible if user can delete the etcd snapshot resource
          • restore snapshot via new operation
            • visible if user can create the operation CR
      • cluster actions
        • take snapshot via new operation
          • visible if user can create the operation CR
        • restore snapshot - model updated with new operation
          • visible if user can create the operation CR
      • snapshot configuration
        • TBD automatic snapshots, snapshot location, metrics
    • certificate rotation
      • cluster actions
        • rotate - model updated with new operation
        • visible if user can create the operation CR
    • encryption key rotation
      • cluster actions
        • rotate - model updated with new operation
        • visible if user can create the operation CR
  • TBD Users can list the different operations
    • users can pause or cancel (delete) operation
