cluster/images/hyperkube: re-add hyperkube busybox style symlinks
Originally symlinks were added with a `--make-symlinks` command discussed in https://github.com/kubernetes/kubernetes/issues/24510 and implemented in https://github.com/kubernetes/kubernetes/pull/24511.
It was backed out in https://github.com/kubernetes/kubernetes/pull/25693 because go binaries don't run in qemu and this breaks cross-building the Dockerfile for arm. In this case, due to running `hyperkube --make-symlinks`.
Lets just add the symlinks manually until the upstream bug is fixed (qemu).

Updated fluentd configuration to spawn multiple threads for processing
(by default, fluentd uses a single thread).

Print/log pointers of structs with %#v instead of %+v
There are many places in k8s where %+v is used to format a pointer to struct, which isn't working as expected.
Fixes#26591
Apparently setting JENKINS_PUBLISHED_VERSION didn't work because it only worked
with `ci/latest`, `release/latest-1.3` or the like, whereas we wanted to pull
specific versions like `release/v1.3.3`. Added a function
`fetch_gci_version_tars` instead.

add union registry for quota
Adds the ability to combine multiple quota registries together. Kube needs this for other types.

Document space shuttle style in controller/volume
Reverts #28813 and #28111.
@xiang90, I really appreciate the effort that went into your PRs (and think, in general, code simplification is a worthwhile effort), but the style in this controller was intentional to ensure that every branch is covered. The verbosity and branchyness of this controller stores a lot of context and knowledge about how this subsystem is meant to function, so we need to put them back in.

Use the CNI bridge plugin to set hairpin mode
Following up this part of #23711:
> I'd like to wait until containernetworking/cni#175 lands and then just pass the request through to CNI.
The code here just
* passes the required setting down from kubenet to CNI
* disables `DockerManager` from doing hairpin-veth, if kubenet is in use
Note to test you need a very recent version of the CNI `bridge` plugin; the one brought in by #28799 should be OK.

Add support to quota pvc storage requests
Adds support to quota cumulative `PersistentVolumeClaim` storage requests in a namespace.
Per our chat today @markturansky @abhgupta - this is not done (lacks unit testing), but is functional.
This lets quota enforcement for `PersistentVolumeClaim` to occur at creation time. Supporting bind time enforcement would require substantial more work. It's possible this is sufficient for many, so I am opening it up for feedback.
In the future, I suspect we may want to treat local disk in a special manner, but that would have to be a different resource altogether (i.e. `requests.disk`) or something.
Example quota:
```
apiVersion: v1
kind: ResourceQuota
metadata:
name: quota
spec:
hard:
persistentvolumeclaims: "10"
requests.storage: "40Gi"
```

e2e-runner: Remove quotes from jq output
Recent GCI e2e test failures suggest that the image name was double quoted when
passed to gcloud. E.g.,
```
09:59:51 - Invalid value for field
'resource.disks[0].initializeParams.sourceImage':
'https://www.googleapis.com/compute/v1/projects/container-vm-image-staging/global/images/"gci-base-53-8530-36-0"'.
The referenced image resource cannot be found.
```
The `-r`, or `--raw-output` option strips quotes from jq's output. With this
change, the output looks like:
```
+ export KUBE_GCE_MASTER_IMAGE=gci-base-54-8650-0-0 # Not quoted
```
@spxtr Can you review this XS PR? All of our e2e jobs are failing due to this.
Also, this was a bug introduced by #29631. I tried several times to duplicate the Kubekins instance locally, but still couldn't get it running. It would be GREAT if Jenkins changes can be tested before getting merged. :)
