This change will not work on its own. Higher level code needs to make sure and call Allocate() before AddContainer is called. This is already being done in cases when the TopologyManager feature gate is enabled (in the PodAdmitHandler of the TopologyManager). However, we need to make sure we add proper logic to call it in cases when the TopologyManager feature gate is disabled.
