Comment 2 for bug 1933444

It's always a same response (always dictionary, I've never seen a list) no matter if "x-auth-all-projects" was provided or not.
The name of this API (as far as i understand it) says that we can get the limits for projects/tenants and if so, we need to fix the respond to be a list and to include "project_id" as a key in dictionaries.
Otherwise, if the only meaning of this API is to get the limits (kind of global Designate limits in general) we need to fix the DOC and probably to replace: "project limits" to "Designate limits" or something to avoid misunderstandings + removing all HTTP irrelevant headers.

It's on design level I think, so I don't really know what should be done here :-(
