Hi all I am currently conducting a PR review (https://github.com/apache/submarine/pull/999) and I have found a multi-tenancy issue about model serving.
The current serving deployment is based on the `default` namespace, however the actual serving service we are doing is on a different tenant service under the operator. So we may need to move the relevant [seldon-secret.yaml](https://github.com/apache/submarine/blob/master/submarine-serve/installation/seldon-secret.yaml) file inside the operator for implementation (I have already created an issue about this https://issues.apache.org/jira/browse/SUBMARINE-1332). We have `submarine-cloud-v2` and v3 under the current master branch. There seems to be a lack of progress on the progress of the operator upgrade. So I thought I'd ask if we should base all our new issue/PR changes on v3 and migrate the operator deployment to v3 from recently after testing and validation?
