K8s 1.4 Release Update

[Phillip Wittrock]

Following is an update on the 1.4 release.

• Branching: We cut the release-1.4 branch today with a beta release. The beta artifacts are available here: https://console.cloud.google.com/storage/browser/kubernetes-release/release/v1.4.0-beta.0/.  We need to switch the release branch tests to go off of this.

• Opening up master: The plan is to continue to keep the master only open to v1.4 milestone changes through the weekend.  On Tuesday we will make a call about generally opening up the branch based on the test stability, open flake count, open issue count.
• Release branch tests are now available on the dashboard:
• https://k8s-testgrid.appspot.com/google-gce#gce-release-1.4
• https://k8s-testgrid.appspot.com/google-aws#aws-release-1.4
• Automated release upgrade tests are still failing
• Started manual upgrade testing today.  This is labor intensive and takes a while.

There has been some confusion around this - to clarify, the intent was to fast forward all commits to master into the release-1.4 branch, and NOT to require cherry picking from master.

There were some other benefits to cutting the branch, such as being able to configure our release-branch test automation to point to it.
