A consistent interface for plugin extended functionality

refactor scheduler extender related API 
- move extender related API from pkg/scheduler/api to pkg/scheduler/apis/extender/v1

- alias extenderv1 to pkg/scheduler/apis/extender/v1

- use NodeScore and NodeScoreList in non-extender logic

a57ac0725a A mapping from predicates/priorities to pluing configuration. 
This PR only implements the mapping, but does not use it. A followup PR will use this mapping to produce a framework configuration that redirects mapped predicates/priorites to be exected as plugins.

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.

641317bdde Updated ContextData and PluginContext with Clone methods. 
This is necessary to be able to clone PluginContext during preemption.

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.

54ac023a53 Scheduler PreBind plugins are currently allowed to return Unschedulable status, which should not according to the KEP and comments. 2019-09-11 14:03:18 -04:00

439a6825e7 need to use local variable so that pluginNameToConfig map can keep correct contents 
because the type of PluginConfig.Args is not pointer.

It also fixed framework_test so that it can test PluginConfig initialization.

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.
