Hypervisor stats do not reflect accurate VCPUs and PCPUs usage, so to have a correct picture we need to use Placement API along with hypervisors. We add VCPUs and PCPUs usage diagrams and Resource Provider tab to display correct stats. Since there is no python client for the Placement API, and the OpenStack SDK doesn't support the endpoints we need, we call the endpoints directly.
