- 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?

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

Add validation preventing recycle of / in a hostPath PV
Adds a validation that prevents a user from recycling `/` when it is used in a hostPath PV

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.

Fix pvc requests.storage validation
A `PersistentVolumeClaim` should not be able to request a negative amount of storage.
/cc @kubernetes/sig-storage @kubernetes/rh-cluster-infra @deads2k
This implements the proposal in:
docs/proposals/secret-configmap-downwarapi-file-mode.md
Fixes: #28317.
The mounttest image is updated so it returns the permissions of the linked file
and not the symlink itself.

Fix GPU resource validation
This fixes scheduling of pods with GPU resources. The change was never upstreamed during the 1.3 beta period, as it got lost in the noise of other changes in our fork. Ooops. I'll submit a cherry-pick request for 1.3.1 as soon as this lands in master.
Because of defaulting, requests are always set if limits are. Thus, the check can never succeed. Instead, make sure that the two values are equal.
Also, remove a few other error messages and remove unnecessary Sprintf calls.

WIP v0 NVIDIA GPU support
```release-note
* Alpha support for scheduling pods on machines with NVIDIA GPUs whose kubelets use the `--experimental-nvidia-gpus` flag, using the alpha.kubernetes.io/nvidia-gpu resource
```
Implements part of #24071 for #23587
I am not familiar with the scheduler enough to know what to do with the scores. Mostly punting for now.
Missing items from the implementation plan: limitranger, rkt support, kubectl
support and docs

Add subPath to mount a child dir or file of a volumeMount
Allow users to specify a subPath in Container.volumeMounts so they can use a single volume for many mounts instead of creating many volumes. For instance, a user can now use a single PersistentVolume to store the Mysql database and the document root of an Apache server of a LAMP stack pod by mapping them to different subPaths in this single volume.
Also solves https://github.com/kubernetes/kubernetes/issues/20466.
Had to move other things around too to avoid a weird api ->
cloudprovider dependency.
Also adding fixes per code reviews.
