Oh yeah that's probably because of the on-going doc migration[1].

Yes.

Rally benchmarks put loads the various APIs and gather some metrics about 
the execution (time, failures...)

Keystone is indeed involved and the token was at that time UUID token.

Telemetry wasn't set up, I guess this would have killed Rabbit earlier in the tests.
The split between notification and RPC messaging is interesting in this area.
