    Update scheduler rpc API version.

    Commit de09c1866b9138610914ddaaebb9b030884d1e28 updated the scheduler
    rpc API but did not account for rpc API versioning. This patch fixes it
    up. It updates the manager to reflect that it implements '2.1' and is
    now backwards compatible with the old method signature. The client side
    rpcapi now indicates that it requires '2.1' when sending the new
    image_id argument.

    Fix bug 1052670.
