commit 2c63cae921d024f39f7d14459873d20caa5cf9e0

    Allow resizes and migrates during live upgrade
    
    This patch completes the changes needed to havana's compute rpc api to
    allow live upgrades to icehouse.  Specifically, these changes are needed
    to allow resizes and migrates to work.  Before havana compute nodes get
    put in a mixed environment with icehouse compute nodes, they need to be
    speaking version 3.0 messages.
    
    Change-Id: If09bd38c9d8c3beb5b95107c497699dec47aa3ef
    Closes-bug: #1258253


Unfortunately, it doesn't work completely as expected.  There are some messages that claim to be sending 3.0 messages, but have the data in the wrong format.
