Skip pods that refer to PVCs that are being deleted
**What this PR does / why we need it**:
New check was added to `Schedule()` to make sure that a scheduled pod refers to existing PVCs that are not being deleted.
In 1.9 we plan to add a new feature that uses finalizers on PVC to protect PVCs that are used by a running pod from being deleted. This finalizer will be removed when all pods that use a PVC are finished or deleted. See https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/postpone-pvc-deletion-if-used-in-a-pod.md for details.
I needed to pass `pvcLister` to `GenericScheduler`.
UX:
```
$ kubectl describe pod
...
Type Reason Age From Message

```
**Release note**:
```release-note

Refactor Priority Reduce functions
- Reducing the duplicated reduce function by introducing a reduce
function generator that generates common reduce functions.
- Remove logs from reduce function, so it's purely calculating scores.
- Optimize the reduce functions by removing unnecessary conversion to
float64.

Optimize Repeated registration of AlgorithmProvider when ApplyFeatureGates
**What this PR does / why we need it**:
modified ApplyFeatureGates() just add/del features, cancel the register of all AlgorithmProvider.
there is Repeated registration of all AlgorithmProvider when ApplyFeatureGates() runs;
AlgorithmProvider have already registered when package defaults loaded;
I think ApplyFeatureGates() is just add/del features, it needn't register all AlgorithmProvider again

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme
This serves as
- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
left depenncies.
The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.
