Prepare for move zz_generated_deepcopy.go to k8s.io/api
This is in preparation to move deep copies to with the types to the types repo (see https://github.com/kubernetes/gengo/pull/47#issuecomment-296855818). The init() function is referring the `SchemeBuilder` defined in the register.go in the same packge, so we need to revert the dependency.
This PR depends on https://github.com/kubernetes/gengo/pull/49, otherwise verification will fail.

Fix: check "ok" first to avoid panic
Check "ok" and then check if "currState.pod.Spec.NodeName != pod.Spec.NodeName", here if currState is nil, it will panic.

Aggregated used ports at the NodeInfo level.

Aggregated used ports at the NodeInfo level for `PodFitsHostPorts` predicate.
```
If we get the scheduling metrics, which is "SchedulingAlgorithmLatency, E2eSchedulingLatency, BindingLatency". The E2eSchedulingLatency should be the sum of SchedulingAlgorithmLatency and BindingLatency, while we found E2eSchedulingLatency is almost the same as E2eSchedulingLatency for some optimization.

Fixed potential OutOfSync of nodeInfo.
The cloned NodeInfo still share the same resource objects in cache; it may make `requestedResource` and Pods OutOfSync, for example, if the pod was deleted, the `requestedResource` is updated by Pods are not in cloned info. Found this when investigating #32531 , but seems not the root cause, as nodeInfo are readonly in predicts & priorities.
Sample codes for `&(*)`:
```
package main
import (
"fmt"
)
type Resource struct {
A int
}
type Node struct {
Res *Resource
}
func main() {
r1 := &Resource { A:10 }
n1 := &Node{Res: r1}
r2 := &(*n1.Res)
r2.A = 11
fmt.Printf("%t, %d %d\n", r1==r2, r1, r2)
}
```
Output:
```
true, &{11} &{11}
```
