Support CLONE_VOLUME

[ElectroshockGuy]

Why you need it?

failed to provision volume with StorageClass "open-local-lvm": CSI driver does not support clone operations: controller CLONE_VOLUME capability is not reported

How it could be?

open-local already implements CSI volume cloning, why not enable it?

what version of open-local?

[ElectroshockGuy]

version: open-local v0.7.0

Hi, apologies for the misunderstanding on my part. It appears that pv-clone.md is only a design document (#100). May I ask if there are any plans to support clone volume in the near future?

[peter-wangxu]

currently no，the current way is to take snapshot and create pv from it.
