ec83143342 scheduler: merge Reserve and Unreserve plugins
Previously, separate interfaces were defined for Reserve and Unreserve
plugins. However, in nearly all cases, a plugin that allocates a
resource using Reserve will likely want to register itself for Unreserve
as well in order to free the allocated resource at the end of a failed
scheduling/binding cycle. Having separate plugins for Reserve and
Unreserve also adds unnecessary config toil. To that end, this patch
aims to merge the two plugins into a single interface called a
ReservePlugin that requires implementing both the Reserve and Unreserve
methods.

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.

This make it easier to catch the issue during the compilation, also,
this also align with other plugins, i.e. plugin of "InterPodAffinity".
