Clarify the bandwidth authority spec to include client and server/service paths
It's unclear whether the "average stream capacity regardless of path" includes the path from the client to the entry, and the exit to the internet server. Pragmatically, in the current design, it has to include client and internet server. (Or, in the case of onion services, client and service.)
I don't know if this affects our design at all, but it should be clarified in the spec.
