Automatic merge from submit-queue

Set deserialization cache size based on target memory usage

**Special notes for your reviewer**:

This is the PR we talked about yesterday.

**Release note**:

```release-note
To reduce memory usage to reasonable levels in smaller clusters, kube-apiserver now sets the deserialization cache size based on the target memory usage.

Cluster Federation

Kubernetes Cluster Federation enables users to federate multiple Kubernetes clusters. Please see the user guide and the admin guide for more details about setting up and using the Cluster Federation.

Building Kubernetes Cluster Federation

Please see the Kubernetes Development Guide for initial setup. Once you have the development environment setup as explained in that guide, you also need to install jq

Building cluster federation artifacts should be as simple as running:

make build

You can specify the docker registry to tag the image using the KUBE_REGISTRY environment variable. Please make sure that you use the same value in all the subsequent commands.

To push the built docker images to the registry, run:

make push

To initialize the deployment run:

(This pull the installer images)

make init

To deploy the clusters and install the federation components, edit the ${KUBE_ROOT}/_output/federation/config.json file to describe your clusters and run:

make deploy

To turn down the federation components and tear down the clusters run:

make destroy

Ideas for improvement

  1. Split the build phase (make recipe) into multiple phases:

    1. init: pull installer images
    2. build-binaries
    3. build-docker
    4. build: build-binary + build-docker
    5. push: to push the built images
    6. genconfig
    7. deploy-clusters
    8. deploy-federation
    9. deploy: deploy-clusters + deploy-federation
    10. destroy-federation
    11. destroy-clusters
    12. destroy: destroy-federation + destroy-clusters
    13. redeploy-federation: just redeploys the federation components.

  2. Continue with destroy phase even in the face of errors.

    The bash script sets set -e errexit which causes the script to exit at the very first error. This should be the default mode for deploying components but not for destroying/cleanup.
