Complete the Architecture Spec for the following use case, and present it to the team for estimating:

In the cloud we can no longer access the PostgreSQL database directly on the AppSRE platform, and we cannot ask on-premise users to perform basic admin functions via direct database access. Therefore, we need tools that enable admins for c.rh.c and on-premise to perform the following functions (and possibly others) without requiring direct database access:

• Create one or more namespaces
• Delete one or more namespaces
• Create one or more users
• Delete one or more users
• Assign permissions to users
• Delete one or more collections
• Delete one or more collection versions
• Cancel one or more tasks

One option to explore might be the Pulp CLI.
