[Feature] Volume Shortcuts and k3d-managed volumes

[iwilltry42]

Changes

Added

• Volumemount-Shortcuts
  • Use some destination shortcuts with the --volume/-v flag that k3d automatically expands
    • k3s-storage -> /var/lib/rancher/k3s/storage
    • k3s-manifests -> /var/lib/rancher/k3s/server/manifests
    • k3s-manifests-custom -> /var/lib/rancher/k3s/server/manifests/custom (not K3s default: this is just some sub-directory inside the auto-deploy manifests directory which will also be parsed)
    • k3s-containerd -> /var/lib/rancher/k3s/agent/etc/containerd/config.toml (use with caution, K3s generates this file!)
    • k3s-containerd-tmpl -> /var/lib/rancher/k3s/agent/etc/containerd/config.toml.tmpl (used by K3s to generate the real config above)
    • k3s-registry-config -> /etc/rancher/k3s/registries.yaml (or just use --registry-config)
• k3d-managed volumes
  • non-existing named volumes starting with a k3d- prefix will now be created and managed by k3d

Need actual examples. Tried this and got error:

(base) ~ k3d cluster create --servers 2 -v k3d-data:k3s-storage foobar
WARN[0000] No node filter specified
FATA[0000] Failed Cluster Configuration Validation: failed to validate volume mount 'k3d-data:k3s-storage': volume mount destination doesn't appear to be an absolute path: 'k3s-storage' in 'k3d-data:k3s-storage'
