068c69d743 Skip PreScore when the TopologySpreadConstraints is specified
`DefaultPodTopologySpread` need't score when the `TopologySpreadConstraints`
is specified.

`PreScore` needn't do this as well, this cut off the cost of `PreScore` if
possible.

9ebd872e71 Explicitly declare the interfaces for extension points
This make it easier to catch the issue during the compilation, also,
this also align with other plugins, i.e. plugin of "InterPodAffinity".

d353cc1532 Use maxSkew in PodTopologySpread scoring as tolerance to skew
This new approach results in better spreading for small number of pods, while still giving meaning to the maxSkew parameter.

42fbb1d72f Define the thresholds per the size of container images
Given the assumption that 90% of images on dockerhub drops into this range (23~1000)MB,
this assumption is based on the container images instead of the pod.

pod might hold multiple container images, it's better to multiply the assumption by the size
of container images.
