Use nested allocation candidates
Placement added support for allocation candidates query against nested resource provider trees in microversion 1.29. Nova's scheduler report client needs to start using the new microversion to enable adding support for vGPUs, bandwidth and cyborg devices reported as nested RPs under the compute node RP.
Work items in dependency order:
* Add support for microverion 1.28 (consumer generation) in scheduler report client.
* Add support for microversion 1.29 (nested allocation candidates) in scheduler report client.
* Write functional tests that verifies that scheduling against a nested tree is possible. Fix the bugs.
* Write functional tests that verifies that various server moving operation handles nested allocation properly (migrate, resize, resize-same-host, evacuate, live-migrate, unshelve). Fix bugs.
