Helm Fixes for GKE deployment (#963)

* Helm Fixes for GKE deployment
 - Make PV and PVC controllable by values.yaml, GKE does not need a VPC. Config for PV and VPC are split up.
 - Added storageClassName to PV and PVC configuration, GKE need it.
 - Deployment, added startupProbe as the downloading and writing of the IRMA schema on the PV cause container creation timeouts.
