Explicitly disable gRPC idle timeout

The idle timeout was disabled, but has been enabled by default in google.golang.org/grpc v1.59. The kubernetes-csi-addons operator acts similarly to the Kubernetes external-provisioner, and benefits from having a functional gRPC connection open to the csi-addons sidecars that run alongside CSI-drivers.
