    xenapi: implement get_console_output for XCP/XenServer
    
    If an administrator has enabled the logging of guest
    consoles on XCP/XenServer, this enables nova to return
    the last MB of those logs to the user.
    
    The management of the logs on the server is a little
    tricky, and will be sorted in a later patch.
    
    Change was based on this previous idea:
