This patch adds a new filter for the cinder scheduler that can interpret two new properties provided by backends, 'filter_function' and 'goodness_function'. A driver can rely on cinder.conf entries to define these properties for a backend or the driver can generate them some other way. An evaluator is used by the filter to parse the properties. The 'goodness_function' property is used to weigh qualified backends in case multiple ones pass the filter. More details can be found in the spec: https://review.openstack.org/#/c/129330/ Implements: blueprint filtering-weighing-with-driver-supplied-functions DocImpact: New optional backend properties in cinder.conf. New filter and weigher available for scheduler. Change-Id: I38408ab49b6ed869c1faae746ee64a3bae86be58
