    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.

    It uses the image properties that are copied into system metadata
    to detect if "agent_enabled"=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_enabled_default".

    This opens up the path to using config drive or the metadata
    service with cloud-init to perform tasks like file injection
