let's make this func more generic, set csi.storage.k8s.io/serviceAccount.tokens as a parameter, thanks.

rename as stripSecrect(secretFieldNames []string)

This will be conflict with the protosanitizer.StripSecrets function in csi lib

return req.String()
}

volumeContext["csi.storage.k8s.io/serviceAccount.tokens"] = "***stripped***"

b, err := json.Marshal(parsed)
if err != nil {
return req.String()
}

return string(b)
