Support the coscheduling plugin of scheduler-plugins

[tenzen-y]

I added the implementation for the coscheduling plugin of kubernetes-sigs/scheduler-plugins.

ref: https://github.com/kubernetes-sigs/scheduler-plugins/tree/master/pkg/coscheduling

So I modified the following:

• Added PodGroupControl interface inspired by https://github.com/kubeflow/common/blob/4dbf18c85417b54158914d1d01c1744b4e3542f2/pkg/controller.v1/control/pod_control.go#L53-L65.
• Added VolcanoCtrl implemented PodGroupCtrl interface. The logic is the same as before.
• Added SchedulerPluginsCtrl implemented PodGroupCtrl interface.

Follow ups:

• Add E2E tests

Part-of: #500

I will add the integration tests to this PR.

I wonder if @denkensk could give a sanity check as one of the authors of the coscheduling plugin.
