Can you please add 'externalAccess' here: https://dell.github.io/csm-docs/docs/csidriver/installation/helm/powerflex/#install-the-driver. Also, X_CSI_POWERFLEX_EXTERNAL_ACCESS to https://dell.github.io/csm-docs/docs/csidriver/installation/operator/powerflex/#install-driver.

CSI PowerFlex driver Version 2.9.0 and later supports the ability to configure NFS access to nodes that use dedicated storage networks.

To enable this feature you need to specify `externalAccess` parameter in your helm `values.yaml` file or `X_CSI_POWERFLEX_EXTERNAL_ACCESS` variable when creating CustomResource using an operator.

The value of that parameter is added as an additional entry to NFS Export host access.

For example the following notation:
```yaml
externalAccess: "10.0.0.0/24"
```

This means that we allow for NFS Export created by driver to be consumed by address range `10.0.0.0-10.0.0.255`.

## Storage Capacity Tracking
CSI-PowerFlex driver version 2.8.0 and above supports Storage Capacity Tracking.
