Ability to add users and control permissions per table.

Is your feature request related to a problem? Please describe.
If you have an organization, where you want different people (or teams) to be able to view different tables. In addition you want want to allow those who view a table, ability to edit (add / remove) and drop table altogether. It's unclear to be how this may be achieved currently with QDB.

Describe the solution you'd like
It would be cool if users can be created - thus allowing access to the DB and for each user to be able to control their view / edit / delete permissions. If this can be done through the UI for an admin user - even better.

Describe alternatives you've considered
@ideoma suggested changing FS permissions on directory, so this could be definitely one approach I guess. Alternatively I was thinking that exposing the data via REST (or another layer) and handling permissions there is another way of acheving similar results. Downside being that other users don't know / interact directly with the backend.

Additional context
None.

No files, tests, or entry points are named. Start by clarifying QDB's current access model and whether the scope includes user creation, per-table permissions, and an admin UI or REST layer; done requires an agreed design and tests covering the selected permission boundaries.
