manual API changes and code refactoring 
- add Policy API to pkg/scheduler/apis/config and staging/src/k8s.io/kube-scheduler/config/v1
- dual-register Policy as apiGroup "v1" and "kubescheduler.config.k8s.io
- move/merge pkg/scheduler/api to pkg/scheduler/apis/config/...
- alias schedulerapi to pkg/scheduler/apis/config
- alias legacyapi to pkg/scheduler/api
- eliminate latest.Codec; use scheme.Codecs instead
- unit tests to verify Policy YAML with version "v1" or "kubescheduler.config.k8s.io/v1" can be loaded properly
- update api/api-rules/violation_exceptions.list

314ec4e504 feat(scheduler): consolidate ScoreWithNormalizePlugin into ScorePlugin 2019-09-26 10:19:06 +08:00
Abdullah Gharaibeh
37b9e6d1ea An interface that allows pre-filter plugins to update their pre-calculated. 
This is needed to allow efficient preemption simulations: during preemption, we remove/add pods from each node before running the filter plugins again to evaluate whether removing/adding specific pods will allow the incoming pod to be scheduled on the node. Instead of calling prefilter again, we should allow the plugin to do incremental update to its pre-computed state.

89f936f6ac Modified the Filter interface to pass in nodeinfo instead of node name. 
This is necessary to support preemption, which relies on passing modified nodeinfo objects to the filters to simulate evicting lower-priority pods.

3c1f8a8c4e [Framework] Add UnschedulableAndUnresolvable status code 
The status can be used by (Pre)Filter plugins to indicate that
preemption wouldn't change the decision of the filter.
