[Issue 5857][Helm Chart] - Support to existing Storage Class with StorageClassName (#5860)

Browse Source 
Fixes #5857 

### Motivation

With current aproach for specifying storage class in persistent volume claim it's not possible to customize the provisioner parameters. If the property 'storageClass' is declared the chart always create a new storage class with hardcoded parameters.

### Modifications

A property 'storageClassName' was added to support an existent storage class.

### Verifying this change

This change is a trivial rework / code cleanup without any test coverage.
