Region for cross-region mounting

[ruszu]

Is your feature request related to a problem? Please describe.
I have VPC-1 in Virginia and VPC-2 in Mumbai. AWS EFS was created in Virginia. I would like to mount EFS from Virginia to the k8s pods in Mumbai EKS. According to the AWS doc, I need to set region in the efs-utils.conf in the nodes in Mumbai.

Describe the solution you'd like in detail
As a workaround we use userdata script to modify conf file, but it would be better to do it by the helm chart.

Hi @ruszu, we are already working on it internally. In EFS CSI Driver, we had a plan of implementing new mount option as region which can be specified in the Storage-class and PV file for Dynamic and Static Provisioning respectively and leverage the cross region.
Will notify this issue with latest updates soon.
