Bigbang values queried via service account as secretRef

Feature Request

Support setting Bigbang values, including registry credentials via service account queried through vault csi-driver volume mount .... ideally this would be distributed into subcharts as well.

https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/values.yaml#L21

Why

What is the use case for the feature you are requesting? What are you trying to solve?

I want to push bigbang values.yaml to vault and more securely query vaules/creds via vault service account through secretRef.

Proposed Solution

This would probably require a look at syncing service account via flux helm-controller.

Or, add Bigbang job to query for vault values/credentials via service account.
