Provide documentation on how to migrate from the (deprecated) OpenEBS 3.x Helm Chart to the new 4.x version #4353

Is your feature request related to a problem? Please describe.

OpenEBS has deprecated their legacy do-everything helm chart, as seen here. This is unfortunately the chart currently used by k0s, and while there are docs on how to move from the embedded OpenEBS chart to a user-configured one, those docs still presuppose that you will be migrating to version 3.x of the do-everything chart.

There is a new OpenEBS localpv hostpath provisioner chart, here, that starts from version 4.0. However, it uses a different chart name + values configuration, and so the current documentation is insufficient.

Describe the solution you would like

Documentation on how to perform this migration would be greatly appreciated. An automatic migration of the storage extension version from 3.x to 4.x would be wonderful too, of course.

Describe alternatives you've considered

There's actually a successor openebs/openebs@4.0.1 chart at https://github.com/openebs/openebs/tree/main/charts (same chart name, different repository URL) - that would be far easier to migrate to than the subchart that only handles local path storage!

Still needs an updated values file + docs though.

fyi, I haven't been able to make the new 4.0.1 chart work with k0s - see: https://github.com/openebs/zfs-localpv/issues/530

Openebs deploys fine, I just can't use it to create PVCs.

EDIT: my issue is fixed - was missing trailing / on the kubelet path 🫤
