Can network-based security tool (e.g., odo) be used as Access Control Layer for FDB?

I met in KubeCon'2019 a startup named `odo` (https://odo.io/database-access/) which provides the user-based fine-granularity access control to database services. They demonstrated with postgreSQL that they can control DB users’ access (like edit or view) without changing database.

It can be an interesting solution for Access Control Layer (ACL) to control which user can access which keyspace in FDB.

If anyone wants ACL, the technique may be helpful.

The issue describes odo's PostgreSQL access-control demonstration and asks whether it could control FoundationDB keyspaces. No files, tests, or entry points are named, so define the scope and implementation location before work can begin.
