[k8s][magnum] Kubernetes In Tree Provider Scheduled for Removal in 1.17


Hi Chris,

Thanks for the sending this out. In Magnum, we have already switched to
the external provider[1]. The only concern for me now, is the cinder
support. Based on understanding, the cinder support in cloud provider
openstack is based on CSI. Is it ready for production now? Are there any
feature gap between the in-tree and CPO? Thanks.
