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

Add kubelet flags for eviction threshold configuration
This PR just adds the flags for kubelet eviction and the associated generated code.
I am happy to tweak text, but we can also do that later at this point in the release.
Since this causes codegen, I wanted to stage this first.

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.

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
This change revises the way to provide kube-system manifests for clusters on Trusty. Originally, we maintained copies of some manifests under cluster/gce/trusty/kube-manifests, which is not scalable and hard to maintain. With this change, clusters on Trusty will use the same source of manifests as ContainerVM. This change also fixes some minor problems such as shell variables and comments to meet the style guidance better.
- Add README.md for node e2e tests
- Add support for --cleanup=false to leave test files on remote hosts and temporary instances for debugging
- Add ubuntu trusty instances for docker 1.8 and docker 1.9 to jenkins pr builder
- Disable coreos-beta for jenkins ci since it is failing - need to investigate
