Explore deploying a single hub with individual groups

[kabilar]

1. For the DANDI, LINC, and BICAN projects we are running 3 separate JupyterHubs.
2. Running a separate hub for each project potentially increases the total base costs compared to running a single hub with separate groups.
3. Let's explore what it would take to run all projects on the same hub, but separate the profiles (and potentially billing) using groups.

I agree that the base cost of running all three as a single hub would be a bit less expensive, maybe $10/day/hub or so base cost.

Here's the challenges I anticipate:

• cleanly separating the costs: If the math can be a little bit fuzzy, not so much of an issue.
• custom auth: I am not sure if groups can have a separate auth mechanism, which will be especially challenging to have custom auth endpoint for dandihub and linc, but GitHub org based for bican.

Thanks for breaking it down, Austin. Let's discuss more over the next few weeks.
