Previously, the verious Merge() policies of the TopologyManager all eturned their own lifecycle.PodAdmitResult result. However, for consistency in any failed admits, this is better handled in the top-level Topology manager, with each policy only returning a boolean about whether or not they would like to admit the pod or not. This commit changes the semantics to match this logic.
