- Prevents kubelet from overwriting capacity during sync.
- Handles opaque integer resources in the scheduler.
- Adds scheduler predicate tests for opaque resources.
- Validates opaque int resources:
- Ensures supplied opaque int quantities in node capacity,
node allocatable, pod request and pod limit are integers.
- Adds tests for new validation logic (node update and pod spec).
- Added e2e tests for opaque integer resources.

Loadbalanced client src ip preservation enters beta
Sounds like we're going to try out the proposal (https://github.com/kubernetes/kubernetes/issues/30819#issuecomment-249877334) for annotations -> fields on just one feature in 1.5 (scheduler). Or do we want to just convert to fields right now?

requests.storage is a standard resource name
The value `requests.storage` is a valid standard resource name but was omitted from the standard list.

Add PVC storage to LimitRange
This PR adds the ability to add a LimitRange to a namespace that enforces min/max on `pvc.Spec.Resources.Requests["storage"]`.
@derekwaynecarr @abhgupta @kubernetes/sig-storage
Examples forthcoming.
```release-note
pvc.Spec.Resources.Requests min and max can be enforced with a LimitRange of type "PersistentVolumeClaim" in the namespace
```
* flocker datasets should be attached using an unique identifier. This
is not the case for the name metadata used by datasetName
* allow only one of datasetUUID / datasetName specified

Split path validation into a separate library
This PR splits path segment validation into it's own package. This cuts off one of the restclient's dependency paths to some docker packages, and completely eliminates its dependency on go-restful swagger validation.

Add AppArmor feature gate
Add option to disable AppArmor via a feature gate. This PR treats AppArmor as Beta, and thus depends on https://github.com/kubernetes/kubernetes/pull/31471 (I will remove `do-not-merge` once that merges).
Note that disabling AppArmor means that pods with AppArmor annotations will be rejected in validation. It does not mean that the components act as though AppArmor was never implemented. This is by design, because we want to make it difficult to accidentally run a Pod with an AppArmor annotation without AppArmor protection.

Add validation preventing recycle of / in a hostPath PV

add validation for PV spec to ensure correct values are used for ReclaimPolicy on initial create
k8 currently allows invalid values for ReclaimPolicy (i.e. "scotto") - this allows the PV to be created and even bound, however, when the pvc or pod is deleted and the recycler is triggered, an error is thrown
```
Events:
FirstSeen LastSeen Count From SubobjectPath Type Reason Message
--------- -------- ----- ---- ------------- -------- ------ -------
36s 36s 1 {persistentvolume-controller } Warning VolumeUnknownReclaimPolicy Volume has unrecognized PersistentVolumeReclaimPolicy
```
New behavior will not allow the user to create the PV:
```
[root@k8dev nfs]# kubectl create -f nfs-pv-bad.yaml
The PersistentVolume "pv-gce" is invalid: spec.persistentVolumeReclaimPolicy: Unsupported value: "scotto": supported values: Delete, Recycle, Retain
```
The serviceAccountName is occasionally useful for clients running on
Kube that need to know who they are when talking to other components.
The nodeName is useful for PetSet or DaemonSet pods that need to make
calls back to the API to fetch info about their node.
Both fields are immutable, and cannot easily be retrieved in another
way.

Basic scaler/reaper for petset
Currently scaling or upgrading a petset is more complicated than it should be. Would be nice if this made code freeze on friday. I'm planning on a follow up change with generation number and e2es post freeze.

Fix pvc requests.storage validation
A `PersistentVolumeClaim` should not be able to request a negative amount of storage.
