shade/openstacksdk has implemented client-side rate limiting on top of keystoneauth for ages and uses it extensively in nodepool. As part of an effort to refactor that code a new approach was devised which was much simpler and therfore suitable for inclusion in keystoneauth directly. The underlying goal is two-fold, but fundamentally is about allowing a user to add some settings so that they can avoid slamming their cloud. First, allow a user to express that they never want to exceed a given rate. Second, allow a user to limit the number of concurrent requests allowed to be in flight. The settings and logic are added to Adapter and not Session so that the settings can easily be per-service. There is no need to block requests to nova on a neutron rate limit, after all.
