Implements blueprint vnc-console-cleanup

 * Creates a unified way to access vnc consoles for xenserver and libvirt
 * Now supports both java and websocket clients
 * Removes nova-vncproxy - a replacement version of this (nova-novncproxy) can be found as described in vncconsole.rst
 * Adds nova-xvpvncproxy, which supports a java vnc client
 * Adds api extension to access java and novnc access_urls
 * Fixes proxy server to close/shutdown sockets more cleanly
 * Address style feedback
 * Use new-style extension format
 * Fix setup.py
 * utils.gen_uuid must be wrapped like str(utils.gen_uuid()) or it can't be serialized
