    Make ssh key injection work with xenapi agent
    
    If there's 'key_data' on an instance, and instance is not Windows, use
    file injection to inject /root/.ssh/authorized_keys.  If a user
    specifies their own /root/.ssh/authorized_keys via 'injected files',
    that will take precedence.
    
    Fixes bug 1152713
    
    Note: Images for Xen that use nova-agent will need to have /root/.ssh
    pre-created with modes 0700 on those directories.
