bump(code.google.com/p/go.net/websocket): 7127eefd36d97b970f5a72d43ef5f4ecf5b1addf

Add code.google.com/p/go.net/websocket to deps.sh and run update.sh.
Add watch mechanism to apiserver

Implemented via HTTP and websocket. A test is present but this isn't
yet wired into anything.

Eventual purpose of this is to allow a scheduler to watch for new pods.
Or allow replication controller to watch for new items it controlls.
Generally, it'll be good to turn everything possible into a push instead
of a poll.
