Monty Taylor 09934718f7 Add support for client-side rate limiting 
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.

This package contains tools for authenticating to an OpenStack-based cloud. These tools include:

  • Authentication plugins (password, token, and federation based)
  • Discovery mechanisms to determine API version support
  • A session that is used to maintain client settings across requests (based on the requests Python library)
