> CSI (Container Storage Interface) is a vendor neutral storage interface specification
for container orchestrators. CSI support is implemented in YARN, Kubernetes and Mesos. Implementing
a CSI server makes it easy to mount disk volumes for containers.
> See https://github.com/container-storage-interface/spec for more details about the spec.
> Until now we used https://github.com/CTrox/csi-s3 server to support CSI specification.
Using an ozone specific CSI server would have the following advantages:
>  * We can provide additional functionalities (as we have access to the internal Ozone
API not just the very generic s3 api).
>  * Security setup can be synchronized.
>  * Increased stability
>  * Simplified deployment (only the minimal set of the components are required to be installed)
> The CSI specification itself is very simple (https://github.com/container-storage-interface/spec/blob/master/csi.proto)
at least the part which is required for Ozone.
> We can use various fuse s3 driver to mount the ozone buckets via s3.
