commit 87593b29e5c337141be65e4430fb95a4f1741afb
Author: Oliver Kurth <okurth@vmware.com>

Optional override for short and long OS names sent from Tools
    
    Added support for customers to override the returned long and short OS
    names through the tools config file. If the setting is present, then names
    gathered by hostinfo will be ignored. The user is responsible for setting
    the appropriate names.
    
    The override will be ignored if the short-name setting is not present in
    tools.conf.
    
    An empty string will be sent for the long OS name if only the short-name
    setting is present.
    
    Appropriate warning msg will be generated in both cases.
    
    Example of the conf setting:
    
    [guestosinfo]
    short-name = centos6-64
    long-name = some long name
