Release Kubernetes v0.2

allow proxy to accept a listen address.  fixes #1220

Typo correction

This commit will be tagged with a v0.2 annotated git tag.

Tested:
- Created a git tag for it, built it and checked output of -version:

    $ git tag -a -m 'Release Kubernetes v0.2' v0.2

    $ make
    hack/build-go.sh
    Building local go components

    $ _output/go/bin/kubecfg -version
    Kubernetes version 0.2, build b47f9af5c9ea770973be1b001adaffbdfcb08618

    $ _output/go/bin/kubecfg -version=raw
    version.Info{Major:"0", Minor:"2", GitVersion:"v0.2", GitCommit:"b47f9af5c9ea770973be1b001adaffbdfcb08618", GitTreeState:"clean"}

- Made sure hack/test-go.sh and hack/test-cmd.sh still pass.

Support configurations for cloudproviders

Passing pod UUID to Kubelet.

Cloud providers may need specific configurations to run properly (e.g.
authentication parameters, uri, etc.).

This patch adds the simplest implementation for passing configurations
to cloudproviders: a new apiserver -cloud_config flag to specify the
path to an arbitrary configuration file.
