/sig scheduling

Why is this needed:

It allows to replace SelectorSpread plugin with a configurable default for the PodTopologySpread plugin.

This is important not just to reduce maintenance burden, but also because the new plugin provides better spreading, both at node level and bigger topologies. Since the score considers all the pods in the cluster, it is able to maintain zone balance even at 5k-node clusters.

Performance benchmarks will be used to ensure scalability is not hurt for vanilla pods.
