Enabled filestore_csi_driver option for autopilot-cluster

[butterthon-dev]

This option appears to have been added in #1166.
However, for some reason it was not enabled on the autopilot cluster, so I have fixed it so that it can be enabled.
Currently it appears to be possible to use Filestore CSI in an Autopilot cluster.

It looks like the provider still does not support this. Could you file a provider issue to fix this first?
