    xenapi: make the xenapi agent optional per image
    
    DocImpact
    part of blueprint xenapi-guest-agent-cloud-init-interop
    
    This adds the ability to decide, per image, if xenapi should use
    the agent for servers created from that image.
    This opens up the path to using config drive or the metadata
    service with cloud-init to perform tasks like file injection
    
    It uses the image properties that are copied into system metadata
    to detect if "xenapi_agent_present"="true" on the image the server
    was created from.
    If the tag is not present, it defaults to the value
    of the new conf setting "xenapi_agent_present_default".
    
    Becuase the above setting defaults to False, it means that
    the xenapi driver no longer waits for the agent by default.
    This fixes bug 1178223
