Supplemental Groups Need for Pod Security Context

[umutcann]

Hi,

We are running file processing batch application on distributed Kubernetes environments. In order to enable restartability on Kubernetes environments for batch apps which include file operations, we are using persistent volume with NFS.

But we are facing permission error during access different clusters. According to our consultant, we need to set SupplementalGroups value over SCDF. But SCDF is not supporting Supplemental Groups value for now.

I opened a pull-request to support that.

#458

May you please overview?

Thanks.
