Fix incorrect  pod spec
Enable public IPs even in not createExternal...

This allows the proxier to portal Public IPs even if the
createExternalLoadBalancer flag is not set.

This also fixes what appears to be a bug in the createExternalLoadBalancer path
wherein multiple PublicIPs would get truncated.
Add a util.Forever variant that ends on a stop channel
Fixes #2681: update to cadvisor 0.6.2
Support remote docker hosts on OS X.

This commit brings two main changes, notably:

Two new options that can be set as environment variables

- DOCKER_OPTS: any arbitrary set of docker options. Example: --tlsverify
- DOCKER_NATIVE: This forces the use of the native docker available.
                 This is most useful if you're on OS X and do not want
                 to use boot2docker.

Now uses 'docker cp' instead of tar piping to transfer files. This
currently must be done by copying the binaries off of the docker volume
and into a local filesystem (/tmp) before a docker cp is done. This
workaround will no longer be necessary after bug fix
https://github.com/docker/docker/pull/8509 makes it into stable.

This was necessary because the tar | tar method was creating corrupted
archives on OS X even with the < /dev/null workaround.
Make credentialprovider less verbose about benign errors.

In particular, a few of the utilities used within the credentialprovider had the pattern:
   glog.Errorf("while blah %s: %v", s, err)
   return nil, err

This change propagates those error message and puts the burden of logging on the caller.

In particular, this allows us to squelch all output during kubelet startup when we are detecting whether certain credentialprovider plugins should even be enabled.
