cluster/images/hyperkube: create symlink for each server
Add a kubelet symlink so that the hyperkube image can appear as a kubelet image. https://github.com/kubernetes/kubernetes/issues/24510
a) it doesn't need it
b) changing CWD to a path with symlinks breaks deep within ginkgo, where it
crafts a relative path to ../../../../../../platforms/amd64/whatever which then
traverses the physical path not the symlinked one, and breaks.
Our `realpath` and `readlink -f` functions (required only because of MacOS,
thanks Steve) were poor substitutes at best. Mostly they were downright
broken. This thoroughly overhauls them and adds a test (in comments, since we
don't seem to have shell tests). For all the interesting cases I could think
of, the fakes act just like the real thing.
Then use those and canonicalize KUBE_ROOT. In order to make recursive calls of
our shell tool not additively grow `pwd` we have to essentially make the
sourcing of init.sh idempotent.

Map secret files into dockerized e2e
Rather than copying the GCE and AWS private keys/credentials to each Jenkins VM, we can put them in credentials and map them through.
This is one half of the change; if the relevant environment variables are set, we'll mount the files in.
cc @fejta @rmmh @apelisse
The codec factory should support two distinct interfaces - negotiating
for a serializer with a client, vs reading or writing data to a storage
form (etcd, disk, etc). Make the EncodeForVersion and DecodeToVersion
methods only take Encoder and Decoder, and slight refactoring elsewhere.
In the storage factory, use a content type to control what serializer to
pick, and use the universal deserializer. This ensures that storage can
read JSON (which might be from older objects) while only writing
protobuf. Add exceptions for those resources that may not be able to
write to protobuf (specifically third party resources, but potentially
others in the future).

kubectl rolling-update support for same image
Fixes#23497.
Enables `kubectl rolling-update --image` to the same image, adding a `--image-pull-policy` flag to remove ambiguity. This allows rolling-update to behave as an "update and/or restart" (https://github.com/kubernetes/kubernetes/issues/23497#issuecomment-212349730), or as a forced update when the same tag can mean multiple versions (e.g. `:latest`). cc @janetkuo @nikhiljindal

Use HOSTNAME in Docker build image tag hash
Fixes#24661 by including `$HOSTNAME` when generating the build image tag hash.
When running the verification checks under Docker, the `$KUBE_ROOT` will be identical across builds, so tags will collide unless we add additional uniqueness. By default, the hostname inside a Docker container is its ID, which should be unique enough for us.
I also deleted a misleading error message from the same check.

Initial kube-up support for VMware's Photon Controller
This is for: https://github.com/kubernetes/kubernetes/issues/24121
Photon Controller is an open-source cloud management platform. More
information is available at:
http://vmware.github.io/photon-controller/
This commit provides initial support for Photon Controller. The
following features are tested and working:
- kube-up and kube-down
- Basic pod and service management
- Networking within the Kubernetes cluster
- UI and DNS addons
It has been tested with a Kubernetes cluster of up to 10
nodes. Further work on scaling is planned for the near future.
Internally we have implemented continuous integration testing and will
run it multiple times per day against the Kubernetes master branch
once this is integrated so we can quickly react to problems.
A few things have not yet been implemented, but are planned:
- Support for kube-push
- Support for test-build-release, test-setup, test-teardown
Assuming this is accepted for inclusion, we will write documentation
for the kubernetes.io site.
We have included a script to help users configure Photon Controller
for use with Kubernetes. While not required, it will help some
users get started more quickly. It will be documented.
We are aware of the kube-deploy efforts and will track them and
support them as appropriate.

Removing call to update-swagger-spec.sh from update-generated-swagger-docs.sh
Fixes https://github.com/kubernetes/kubernetes/issues/24233
Right now `update-generated-swagger-docs.sh` calls `update-swagger-spec.sh`, but `verify-generated-swagger-docs.sh` does not verify swagger spec (that is done by `verify-swagger-spec.sh`).
Hence, `verify-swagger-spec` breaks if it is called after `verify-generated-swagger-docs`.
Fixing it by removing the call to `update-swagger-spec.sh` from `update-generated-swagger-docs.sh`.
This will require users to run both `update-swagger-spec` and `update-generated-swagger-docs` when they update api types, but they already need to run many more scripts (`update-api-reference-docs`, `update-codegen`).
People should mostly be running hack/update-all.sh directly :)

Shorten cluster names in GKE Jenkins on Trusty
We identified an issue that the PD tests in GKE Jenkins on Trusty fail because the PD name is longer than the limit of 63 characters. The PD name embeds the "E2E_NAME" env variable exported in the Jenkins job configuration. This PR shortens that string for all GKE Jenkins on Trusty. As a result, the PD name will meet the limit requirement.

Make etcd cache size configurable
Instead of the prior 50K limit, allow users to specify a more sensible size for their cluster.
I'm not sure what a sensible default is here. I'm still experimenting on my own clusters. 50 gives me a 270MB max footprint. 50K caused my apiserver to run out of memory as it exceeded >2GB. I believe that number is far too large for most people's use cases.
There are some other fundamental issues that I'm not addressing here:
- Old etcd items are cached and potentially never removed (it stores using modifiedIndex, and doesn't remove the old object when it gets updated)
- Cache isn't LRU, so there's no guarantee the cache remains hot. This makes its performance difficult to predict. More of an issue with a smaller cache size.
- 1.2 etcd entries seem to have a larger memory footprint (I never had an issue in 1.1, even though this cache existed there). I suspect that's due to image lists on the node status.
This is provided as a fix for #23323

If "a" is a bash array, then the syntax to append the contents of $line as a
