I still don't understand how this is different from tenants in wip-5073.
Each tenant defines what amounts to a namespace for buckets. Could you
clear this up? I heard you discussing it a little bit during the RGW
team stand-up call, but I can't wrap my head around it.

Secondly, have you given a thought to exact API here, or is it all
hand-waved for now? As you may know, initially I hoped we'd get by
without adding any special syntax for tenants. Just off-load it onto
the authentication system, I thought. That didn't work and now we
have the tenant$user syntax allowed all over.

What I mean by that, a client has to do "swift -U tenant\$user:subuser -K pass"
in 5073, and that looks a bit fraught. I presume you avoided that.

Specifically though, imagine I'm doing "radosgw-admin user info",
what do I get under your plan?

P.S. What repo/branch do you use for this? I know you quoted it before,
but just so we're at the same place.
