Feature - Provide more storage types for persistent volume storage

[hoksanyip]

Is your feature request related to a problem? Please describe.

Currently, there are two options to set the storage engine of persistent volume: using parameters local and hostPath, which in both cases will store the data locally in the nodes themselves. As we are trying to set this up the cloud using server-less containers, this would not be viable. Instead, using CSI-backed storages would be would be nice to have. And given the reasonable standardised interface (for most of the drivers, it works by adding parameters in csi specs key, it can be made quite generic for most, if not all, types of CSI drivers.

Describe the solution you'd like

As an alternative to providing the hostOS in the helm values, add an option to add parameters to csi, for example, instead of the values (for example in https://github.com/abnamro/repository-scanner/blob/main/deployment/kubernetes/charts/resc-database/values.yaml):

hostOS: "windows"
database:
   pvc_path: "/var/resc/mssql/data"
  pvc_size: 10Gi

add an option to specify to store the persistent volumes in AWS EFS CSI:

database:
  ...
  storageType: "csi" 
  csi:
    driver: efs.csi.aws.com
    volumeHandle: [[fs-id]]::[[fsap-id]]

so it can directly be inserted as-is in PersistentVolume resource.
